hi i download above image ansys workbench. and i wanted to use ls-dyna that is in workbench

but when i tried to run the ls dyna the error message comes out like

'the demanded solver was not found in the specified path' what can i deal with it

do i also need to download the ls-dyna student version like below. thank you

Yes, download LS-DYNA also.

but it still didn't work..

Yes, but now you have the LS-DYNA solver installed. Go to the Start Menu and under ANSYS 2022R2 LS-DYNA Student select LS-Run. Use that to submit a .k file to the solver.  Under that same folder is LS-PrePost that you can use to build a .k file of your model and look at the results.

Good luck!

thanks for your reply

but i want to ask you one more question.

can i export .k file in ansys? if i save the ansys file its file type is wbpj.

I'm not an expert at LS-DYNA, I'm an expert at Workbench. I had a quick look in the free Ansys (Student) Workbench and in LS-PrePost and noticed that in Workbench, I can export a Nastran file and in LS-PrePost I can import a Nastran file.  I often do meshing in a Modal analysis block and Export Nastran file then open that in Femap where I finish preparing the file to submit to the Nastran solver.

On a paid Ansys Workbench license, LS-DYNA is an analysis system that you can drag into the Project Schematic, just like you can with Explicit Dynamics. This feature is not included in the Student license.

Hello, I am facing the same issue. Is there any solution available now? Thank you

I think the best step-by-step solution for this problem is already available in the following forum post: /forum/forums/topic/error-inside-ansys-ls-dyna-an-error-occurred-inside-the-solver-module-general-error/

I'd the same problem with our license and solved it following that process. Also, after installing, double check if your license server is properly defined.

I hope it helps
