FEA Specialists-take note! How to get the most out of your Abaqus tokens

Dassault is one of the world’s top enterprise software vendors by revenue, and the largest EDT (engineering design tool) supplier. Abaqus is one of their Finite Element Analysis (FEA) products which is widely used for simulations for computer-aided engineering, or CAE. Abaqus was acquired in 2005 by Dassault, and there are 2 license manager options: Dassault’s own product DSLS or Flexera’s Flexnet which is designed to handle token licenses. The token system works quite well for Abaqus, because of the nature of FEA software, which is often run on multiple processors with no or only occasional intervention by the user who scheduled the job. The number of tokens required for a job is dependent on:-

  • the number of simultaneous users
  • the number of parallel processors (CPUs or GPU) that are needed
  • at least 1 token for the CAE pre-processor, depending on number of users

So, while using multiple parallel processors will cut down the time to run the simulation to a fraction of the time it would run with a single CPU, there is an extra cost incurred for each processor used. Below is an illustration of token costing for various Abaqus products:-

Keeping track of token usage can be quite a complex task, and is even more complex when you are running FEA software on multiple CPUs. It can also be a challenge weighing up time taken to process the simulation against the cost of tokens. This is why GPUs have become so popular for intensive computations like FEA.  Tests by Abaqus working in tandem with Nvidia have found that Abaqus Standard runs 3.7 times faster when using a GPU.

Not only is processing time faster, it is cheaper. The token calculation when using one GPU in addition to the CPUs is the same as for the CPUs without a GPU. In other words, looking at the graph above, both methods will use 12 tokens, but results are produced in 1/4 of the time. The amount of acceleration improves for very complex calculations and very high numbers of degrees of freedom (DOF), and may not make a marked difference for smaller computations with a smaller number of DOFs.

This token pricing model applies irrespective of the number of CPUs utilized, as the graph below, illustrates.

The improvement in processing time is shown below as this graph from a white paper by Nvidia illustrates, based on a study at Rolls Royce.

Possibly an even more important benefit is the energy savings from using the energy-efficient GPUs. The graph below, taken from the same white paper, shows energy savings when a GPU is added to the computation.

It clearly makes good sense to start incorporating GPUs into any complex calculations, such as FEA, where the software products cater for it.

There is further good news for Simulia customers, because Dassault has come up with a new token licensing scheme for three additional products, namely Isight, Tosca and FE Safe, which have been bundled together in an extended licensing scheme.

Good News for OpenLM Customers

Customers who use Abaqus have been able to apply OpenLM in managing their Abaqus licenses and tokens for some time. We are pleased to announce that we have recently enhanced our product in answer to a request from a leading research company who use OpenLM to manage their licenses. They asked us to provide license management for the Nvidia GPUs; Nvidia provides a license manager, but for ease of use, the company wanted just one tool to manage the Nvidia licenses as well as their computational software. It must be noted that the Nvidia license manager does not report on usage, an essential requirement for control and optimization. We have been able to develop this solution and it is now available for any of our customers who apply GPUs in their IT environment. We recognise that GPUs are used for a variety of applications, from crypto mining to VDI (virtual desktop infrastructure) installations. Even more conventional engineering tools, such as AutoCAD, are being boosted by the use of GPUs. Now their licenses can be managed through OpenLM as well.

How a Company Got 20/20 Vision into their Engineering Software Licenses

Engineering software is generally very expensive, and most organizations enter perpetual license agreements that are based on the number of concurrent users, rather than buying a license per user. This can achieve considerable cost savings, but there are many companies that do not realise that there are even more savings to be had.

One of our customers, a US company that specializes in transportation and mobility solutions for the 21st century, were frustrated by the lack of visibility into how their engineering tools, which included ArcGIS and AutoCAD, were being used. The license management software provided by the vendors did not enable the license administrator to know whether licenses were booked out were actually being used. While it was important to know this at any time, it became especially important when other users were trying to check out licenses and were getting denied. What the system administrator needed was license management software that gave him real-time insights into what was happening, as well as comprehensive reporting which could be presented to management of how efficiently licenses were being managed.

After investigation and evaluation of software applications in the market that could offer a better solution than the vendor products, the company selected OpenLM. OpenLM’s core product contained all the features that were needed for effective license management. Once the product was implemented, the company was able to accomplish considerable time and cost savings. Idle licenses could be identified and harvested back into the license pool to prevent denials. This has resulted in an excellent ratio of three users per software license. Planning for license renewals is much easier, with detailed reporting available that analyses the current usage and indicates whether more licenses are needed or whether the pool can even be reduced. Another benefit is that only one license management tool is needed to manage the different software engineering products, instead of having to open a license manager for each product.

ESRI introduces ArcGIS for AutoCAD

ESRI has launched a new plug-in application for AutoCAD(v2013 or 2014) that allows for you to access and create GIS data via services from ArcGIS for Server and ArcGIS Online. From within the domain, access to GIS maps, map services, image services, and feature services are now made MUCH easier.

 

An additional selling point of the software, it allows you to edit data that’s been stored locally within the AutoCAD drawing itself or exported from ArcGIS for Desktop.

Both ESRI Desktop software and all Autodesk software are using the FLEXnet publisher for licensing. This allows sites that use both software to fully control and manage the access to licenses by using OpenLM Software.

AutoDesk FlexNet feature codes, March 2012

Feature codes

FlexNet (FlexLM) uses a predefined set of codes in order to manage multiple licensed Features. Each of these features is given a unique code, by which FlexNet grants license requests, and keeps track of the license pool.

OpenLM Also makes use of these feature codes during FlexLM reporting in order to monitor and optimize Autodesk license usage. As versions progress and features are added, the code tables need constant updating. The following is a complete list of AutoDesk codes, updated to March 2012. It was taken from Autodesk’s official site.

Guide to update Autodesk Network License Manager IPv6 for 64-bit Windows OS

Requirements: There are certain pre-requisites or requirements which must be fulfilled before upgrading the Autodesk Network License Manager to IPv6 version support.

  • You must have Autodesk Network License Manger already installed on your server before applying IPv6 support update.
  • So, make it sure that installed software is working good otherwise install a new one by referring Network Licensing Guide which is available in Help System.
  • The server must be stopped before carrying out software update or any other administratively critical maintenance activity on Network License Manger server; server should be restarted after the successful completion of activity.
  • You must be logged into the system with administrator rights for stopping, updating and restarting the services on the server.

Limitations: Though this update is very excellent tool but it has following limitations which should be considered while deciding or working with Autodesk Network License Manger.

  • It supports the operating system with 64-bit configuration; supported Operating systems are Microsoft® Windows® Server 2008 and 2008 R2 64-bit, Windows Vista® 64-bit and Windows7 64-bit.
  • This supports either a mixed environment of IPv4/IPv6 or IPv6-only.
  • This implementation does not support IPv4 –only environment.

Updating procedure: You must make it sure that all the requirements are fulfilled for upgrade activity. Now follow the step by step task given below for updating the Autodesk Network License Manger for IPv6 support.

  • Download NLM_IPv6Support_Win64.exe file and save on the desk top of the server.
  • One the desktop of the server, right click on LMTOOLS.exe and choose Run as Administrator; the LMTOOLS program will start.
  • On LMTOOLS select ‘start/stop/reread’ tab and choose stop server and wait for 15 seconds, then close the LMTOOLS program. Your server has stopped now.
  • The default location of Autodesk Network License Manager is C:\Program Files\Autodesk Network License Manager; you have to locate lmtools.exe, lmutil.exe, lmgrd.exe, and adskflex.exe files to take the backup of Autodesk Network License Manager Files.
  • After taking the backup of above mentioned files, double click the downloaded file NLM_IPv6Support_Win64.exe placed on the desktop of the server.
  • The NLM_IPv6Support_Win64.exe file will be extracted automatically on ‘C:\install\Autodesk\NLMIPv6Support_Win64’ location; extracted updated files are lmtools.exe, lmtools.exe, lmutil.exe, lmgrd.exe, and adskflex.exe.
  • Copy all above mentioned updated files and paste them into existing Autodesk Network License Manager Folder whose default location is C:\Program Files\Autodesk Network License Manager\.
  • System will prompt for replacing the existing file; click yes to confirm.
  • Right click again on LMTOOLS.exe available at desktop and choose run as Administrator.
  • On LMTOOLS program click Start/Stop/Reread tab and choose start server tab; this will restart your server with updated support to IPv6 on 64-bit windows operating systems.

Problem/Error with AutoCAD network license management: “A valid license could not be obtained by the network license manager”

Details:

You can face above problem frequently on AutoCAD 2007 based products when you are working in an organization where:

  • Concurrent licensing scheme is implemented through server/client networking mode.
  • Network bandwidth is low.
  • Network latency is high or connected through VPN.

All of the products based on AutoCAD 2007 contain licensing enhancements which tend to increase network latency and bandwidth utilization of the network. Therefore, you can face this problem while trying to claim the license of the program from the License Manager Server. Earlier versions of AutoCAD products i.e. older than 2007 release were not observing this problem. In this problem, first you are presented with a FLEXlm license finder dialogue box during license obtaining process followed by a message stating:

“A valid license could not be obtained by the network license manager.

Error [1.5. -15]”

In some other products you can receive a bit different message as given below:

“A valid license could not be obtained by the network license manager.

Error [1.5. -18]”

Reasons for Error:

A network throughput or data rate of the link is the main reason for this error especially in case of heavy applications like AutoCAD 2007. Reasons can be summarized as below:

  • Low Bandwidth of the connection i.e. Dial-up connection or low speed ISDN/DSL connection.
  • High Network Latency i.e. VPN
  • Response waiting time of the application/program

One or more of the above reasons can be the root cause of this problem. This problem has recommended solutions which given below.

Solutions:

  • Recommended solution for this problem is either increase in the bandwidth of the connection or decrease in the network latency or enhancement in both parameters.
  • By modification of the response waiting time counter/value which is used as the last resort for the solution of this problem. This is a stepwise procedure to modify the response waiting time counter. Here is the stepwise procedure for the same:
  1. Right click My Computer and choose properties.
  2. On system property dialogue box choose advanced tab.
  3. Click on the environment Variables
  4. On environment variable dialogue box choose system variables field and hit the new button
  5. A new system variable dialogue box with two fields appears; put “FLEXLM_TIMEOUT” in variable name and put 1000000 in variable value field.
  6. Click OK on all three dialogue boxes to close them
  7. Launch the AutoCAD application

 

 

 

 

 

 

 

 

If the problem persists, increase the variable value in multiples of 1000000 micro seconds and reach to the value which gives you satisfactory communication results.

Autocad for MAC!!!

Autodesk announce the release of Autocad 2011 for MAC. It runs natively on the OS X platform with a MAC style interface.

Check the announcement at Autodesk site.

This version does not yet supports network licensing (floating/concurrent licensing) such as the Windows version that uses FLEXlm (FLEXnet) floating licensing.

Another important point to consider is that this initial version of Autocad for MAC does not yet includes all the functionality included in the Windows version. I assume that will be solved very soon.

Is it another crack in the Microsoft dominance in the organizational market?
