Using LS Dyna 16.1.1 with ansys 25R2: Licence issue

    • roberto.scipioni

      How do I solve this?

      Details:

      ==============

      OS: Almalinux

      Ansys version v252

      Downloaded LSDyna 16.1.1 smp_d     separately

      Used INSTALL attached to installer to install Ansys2025R2

      ===================================

      Any idea?

      Kind regards

      Hi Roberto

      Just to make sure - are you using Workbench (25R2 runs 14.1 I think by default so how do you run 16.1 - also whcih Uni are these licences from?)
      For the error - try please to set the enviromental variable called LSTC_LICENSE -> to Ansys.

      All the best

      Thanks.

      1) University of Bath, UK

      2) LSdyna 16.1.1 was downloaded separately

      3) Using Ansys2025R2

       

      I am using

      export LSTC_LICENSE_FILE=network

      export LSTC_LICENSE_SERVER=1055@ansyslm.campus.bath.ac.uk

      export LSTC_LICENSE=ansys

      Hi

      Since using ANSYS SLM we need to use these two only:

      export LSTC_LICENSE=ansys

      export ANSYSLMD_LICENSE_FILE=1055@ansyslm.campus.bath.ac.uk

      Out of interest is it battery model. you are performing with LS-Dyna or?

      All the best

      No idea then why - please wait for other forum members to provide feedback.

        We hope other forum members say from Academia can provide their feedback (non Ansys mem.). 

        In the meantime can you provide some info on the type of licence, if you are using LS-Dyna via workbench or standalone that would help non Ansys forum members especially from academia/Unis to provide some feedback to you.


        Good luck

        Erko

      Would that give some information?

      So, you can run the default solver (14.1) without any issues? I recall a case where a similar thing happened, and it was resolved by upgrading the license manager to 2026R1 version!

      Best,

      Nanda

    • roberto.scipioni

      Yes 14.1 is fine with Ansys2024R2 and Ansys2025R2 however, in using LSDyna 16.1.1 it complaints that the version is not include in the license

       

    • Nanda

      Please try upgrading your license manager to 2026R1, or your whole Ansys package to 2026R1. 2026R1 has R16.1 solver by default!

      Thanks, we may be able to install the version 2026R1 of Ansys so that would solve the issue :-)

    • roberto.scipioni

      I have a question though: The issue is not really the presence of LSDyna 16.1.1 as it can be downloaded separately but the licence. How would would Ansys2026R1 allow LSdyna16.1.1 with the "old" license file?
