The parts imported from LS-DYNA .k file are called as unstructured parts in AUTODYN. The unstructured parts use Lagrange solver if these parts are solid elements, or shell solver if these parts are surface elements, or beam solver if these parts are line elements. If user needs to model material flow of fluids or very large deformation of solids, you can use AUTODYN multi-material Euler solver. To import Lagrange parts (structured or unstructured) into a multi-material Euler part, you need to follow the procedures below: – Create a multi-material Euler part which is large enough to cover the Lagrange parts and the space they will move into. The mesh size should be fine enough to catch the geometric details of the Lagrange parts. – Fill the multi-material Euler part with a generic material such as VOID or Air. – Select the multi-Euler material part, Use FILL -> ADDITIONAL FILL OPTIONS -> PART FILL to fill the Lagrange parts to the newly-created multi-material Euler part. – In the PART FILL window, select the material already in the Euler part such as VOID as the material being replaced in the multi-material Euler part. – Press OK to proceed. – Delete or deactivate the Lagrange parts after they are Part Filled into the Euler part successfully.
