We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Teng,

I checked in our system and the University of Cincinnati account you are associated with only has LSTC LS-DYNA (500 cores) which requires the LSTC license manager.

So, to run LS-DYNA from your machine, you have to point to the LSTC license server by setting the  following 2 environment variables on your Windows machine:

LSTC_LICENSE=network

LSTC_LICENSE_SERVER=hostname_or_ip_address_of_LSTC_license server

If you don't know how to set environment variables in Windows, please Google "how to set environment variables in Windows".

 

To run LS-DYNA, we recommend using LS-RUN. LS-RUN comes with the Ansys installation. If you don't have Ansys installed, you can download LS-RUN here:

https://ftp.lstc.com/anonymous/outgoing/lsprepost/LS-Run/win64/

Here is a video tutorial on how to use LS-RUN:

Note that you can set the license information in LS-RUN and LS-RUN will set the environment variables automatically for you (as long as the Env Var check box is checked):

 

Put the LSTC license server hostname of IP address in the Server hostname field in LS-RUN (see image above).

 

Let me know how it goes.

 

Reno.
