from ansys.dyna.core.pre.dynamaterial import MatRigid, MatFabric from ansys.dyna.core.pre import examples

hostname = "localhost" if len(sys.argv) > 1: hostname = sys.argv[1]

airbag_solution = DynaSolution(hostname) fns = []

path = sys.path[0] + os.sep + "input" + os.sep + "airbag_deploy" + os.sep

path = examples.airbag_deploy + os.sep fns.append(path + "airbag_deploy.k") airbag_solution.open_files(fns) I am getting the below error

Hi pavankumarkonchada, which platform are you using to run this example python file? vscode, jupyter notebook or other platform?
