Run LS-DYNA Using an LSTC_FILE with ANSYS License

    • Christoph Hollweck

      Hello everyone,
      Currently, LS-DYNA is running only in combination with the LSTC_FILE and the LSTC license. Since our LSTC license is limited to just one CPU, I would like to switch to the ANSYS license.

      The current LSTC_FILE contains the following:

      #LICENSE_TYPE: network
      #LICENSE_SERVER: ourservername

      When I change it to:

      #LICENSE_TYPE: ANSYS
      #LICENSE_SERVER: ourservername

      the LSTC license is still being used.

      What do I need to write in the LSTC_FILE to ensure that the ANSYS license is used instead?

      Thank you!

      Christoph

      I would try removing LSTC_FILE and unset the env variables. To use LS-DYNA solver with Ansys license, you only need to define the below env, no need to define the LSTC_LICENSE_SERVER. 

      export LSTC_LICENSE=Ansys

      Note that you will need any additional env you generally set for Ansys license, such as ANSYSLMD_LICENSE_FILE.

      @igandiko Will this allow me to use Ansys HPC Pack to increase the parallel cores for an LSDYNA run?
