Examples

These examples show end-to-end workflows for using PyDyna to create keyword files for LS-DYNA and then solve them from Python. Many are adapted from the LS-DYNA Knowledge Base.

Beer can buckling

This example is adapted from https://lsdyna.ansys.com/example-nonlinear-2/ to run from Python. It is a highly nonlinear problem that whose solution will not fully converge, but that is expected.
