Hello Ansys experts,

my problem is that I would like to use LS-Dyna via Workbench.
I can also drag the container to my main page and do the meshing.
However, when I then go into the LS-Dyna specific analysis settings, I cannot select the solver version. The selection remains at Program Controlled. The yellow background indicating that input etc. is required remains.

I have reinstalled LS-Dyna several times.
Does anyone know the solution to this problem?

In the videos I have seen so far, no input was required. The program-controlled solver version was sufficient.

I use Ansys version 2021 R2.

Thanks in advance for your help.

HI given that you have LSDYNA licenses it should able to solver directly from the installation, is this an acedamic version ? , can you able to check in the installation dir under win64 to see if you fnd any lsdyna_mpp or smp executables, if its not you may want to look for correct installation , the work around is to run the input file via LS-RUN as it might detect the solvers. 

Cheers, Ram

Hello Ram,

Thank you very much for your answer.
I use an "ACADEMIC MULTIPHYSICS CAMPUS SOLUTION" licence on a PC with "Microsoft Windows Server 2016 Standard" as operating system.
In the installation directory you can also find executable files related to LS-Dyna (see picture).

In the main page of Workbench under "Help" and "Info on Ansys Workbench" the entry about LS-Dyna also appears (see picture).

I hope the information is helpful

Best regards

Werner
