Hello,
I have imported a cad file drawn in ANSYS that contains all solid elements. But in LS-DYNA, all solid elements have shell in it, I do not understand why! Also, when I run the model, it gives me a thin shell reference error (snap). Why is that? How can I import the solid model as solid and eliminate this error? Thanks!
Hi @arafat_alam,
So are individual cubes of shell elements being created around each solid element? Could you provide an image of what is happening?
If the solid elements imported correctly and you just want to get rid of the shell elements then that could be an easy fix. You can delete elements by element configuration, so in this case Shell elements.
@negativevolume As you can see from the attached snap, there are shell inside solid. By deleting the element, the model is being reduced - so it doesn't work. Any suggestion?
Thanks. Understood. I have found a workaround. I can create the mesh in ANSYS and then insert that input.k file in LS-DYNA. Thanks.
@arafat_alam see I think that I'm getting confused. You are importing CAD created in Ansys but you say that it contacts elements. I don't work with Ansys so it doesn't make much sense that you would have CAD objects and FEA elements in a single CAD file.
