Run

Use PyDYNA to run LSDYNA locally

Run DYNA using ansys.dyna.core.run on a local machine, this does not require Docker.

Run LS-DYNA using ansys.dyna.core.run

import os
from ansys.dyna.core.run import run_dyna

dynafile = "input.k"
dynadir = os.getcwd()
filepath = run_dyna(dynafile, working_directory=dynadir)
......

How it works

run_dyna attempts to find an installation of the LS-DYNA solver on your machine. It uses the Python dependency ansys-tools-path to discover where LS-DYNA is installed. After installing ansys-tools-path, the location of LS-DYNA can be saved by running save-ansys-path --name dyna {path/to/dyna} so that subsequent usages of run_dyna look there.
