SOLIDWORKS Support Monthly News – March 2018

Hello to all,

Welcome to this new edition of the SOLIDWORKS Support Monthly News, coauthored by members of the SOLIDWORKS Technical Support teams worldwide.


The different methods on how to see who is using SOLIDWORKS PDM licenses

By James Falconer

The old way (up to and including version 2014)

Before SOLIDWORKS Enterprise PDM 2015 you would need to run a SQL Script, or PDM Report to list what licenses were in use (see knowledge base Solution S-08712). Although this method still works with the newest versions of PDM, it does not give the most accurate up to date information. The ‘old way’ had two different methods to gather license usage. The first was to run a SQL script on the SQL server. The other was to use the Report Generator. The Report Generator was much simpler and anyone could be given the right to run it without having to have access to the SQL server to run a script:

The new way (version 2015 and newer)

SOLIDWORKS PDM 2015 introduced the ability to use SNL Licensing and multiple methods to manage licensing using an easy to use interface. SNL licensing is now the current method to view and manage licenses in SOLIDWORKS PDM.

The easiest method to view license usage is to click on the ‘License Usage’ tab in the PDM Admin tool ‘License’ node. Make sure to choose the correct SNL ‘Server’ (1), and the ‘Product’ (2) from the pulldown selections:

The SOLIDWORKS SolidNetWork License Manager displays License Usage as well:

SNL Licensing also provides multiple other tools to view and manage licenses. One tool that we recommend is to view the SNL log (lmgrd.log), which can be viewed by clicking on the ‘View Log’ button under the ‘Server Administration’ tab in the SNL License Manager Tool. You can use this log to see if the number of checked out licenses match what is being shown in the ‘License Usage’ tab:

Another SNL tool is called ‘lmutil.exe’ and is a command line tool that is very powerful and can also list licenses in use on the server. Further information regarding the lmutil tool can be found in knowledge base solution S-044521, as well as the Licensing Administration Guide found in ‘C:\Program Files (x86)\SOLIDWORKS SolidNetWork License Manager\Docs\flexuser\licensingenduserguide.pdf’. Since we utilize the FlexLM application, which is one of the most popular license managers for many applications, we also recommend online searches to see other examples and scenarios which go beyond the scope of our regular licensing tools.

An extra tool for you created by SOLIDWORKS Technical Support (version 2015 and newer)

Technical support also created an application that puts a simple front-end GUI to the lmutil application. The application is stored in knowledge base solution S-070124, and provides some customizability which may be helpful for CAD managers who are looking for more power in viewing their license usage:


Simulation Step-Up Series

Last month, Yannick gave an Introduction to Fatigue analysis. This month, it is Ramesh’s to give an Introduction to Nonlinear analysis.

For the final video of the Simulation Step-Up Series, next month, Joe will give discuss Thermal Analysis.

Noteworthy Solutions from the SOLIDWORKS Knowledge Base

icon - SW Why is the ‘Searchable Text’ option no longer available in SOLIDWORKS® Inspection 2018 Standalone?
SOLIDWORKS® Inspection 2018 Standalone no longer provides the ‘Searchable Text’ project option. That functionality is replaced by the ‘Smart Extract’ tool.
For more information about the the ‘Smart Extract’ tool, see Solution Id: S-074228.

icon - SW When trying to apply an appearance in SOLIDWORKS®, how do I resolve the error: ‘An error has occurred in the script of this page. Error: No such interface supported…’?

When trying to apply an appearance in SOLIDWORKS®, you may see the following error: ‘An error has occurred in the script of this page. Error: No such interface supported, URL: file://[SOLIDWORKS installation folder]/data/search/search.js’
To resolve this issue, follow the steps in Solution Id: S-074082.

Icon - EPDM For testing purposes, how do I restore a customer’s SOLIDWORKS® Manage and SOLIDWORKS PDM Professional integration to a separate system?
To restore a SOLIDWORKS® Manage and SOLIDWORKS PDM integration to a separate system for the purpose of testing, follow the steps in Solution Id: S-074014.

Is there a preferred solver to use when running a Topology study?
In general, the Direct Sparse solvers are recommended for Topology studies. In particular, the Intel Direct Sparse solver provides faster performance for multiple load cases.
The Sparse solvers are recommended over the FFEPlus Iterative solver, which is does not handle large differences in stiffness between neighboring elements as well. The KB solution S-021189 describes this general characteristic of the FFEPlus Iterative solver.
In Topology studies specifically, because the software assigns different relative mass density values to govern stiffness, this can cause elements with high stiffness to be adjacent to elements with very low stiffness.
Note that SOLIDWORKS® Topology studies do not support use of the Intel Network Sparse solver.

 Where can I find examples of the use of Electrical conditions in SOLIDWORKS Flow Simulation to simulate Joule heating?
In attachments to Solution Id: S-073931, you will find the following three example models:

• The attachment ‘Insulated electric cable.sldprt’ simulates the temperature in an insulated electric cable.
• The attachment ‘Resistance.sldprt’ simulates how an electric resistance heats up.
• The attachment ‘Electrical contact.sldasm’ simulates the Joule heating in thin layers of conducting material in contact with each other.

That’s it for this month. Thanks for reading this edition of SOLIDWORKS Support News. If you need additional help with these issues or any others, please contact your SOLIDWORKS Value Added Reseller.
