• streams_container (StreamsContainer, optional) – Result file container allowed to be kept open to cache data.

• data_sources (DataSources) – Result file path container.

• mesh (MeshedRegion or MeshesContainer, optional) – Prevents from reading the mesh in the results file.

• requested_location (str, optional) – Average the elemental nodal result to the requested location (default is nodal).

• poisson_ratio (int or float, optional) – Poisson ratio to be used in equivalent strain calculation.

• read_cyclic (bool, optional) – If true, cyclic expansion is done. if false, it’s ignored.

• average_across_bodies (bool, optional) – For multibody simulations, the stresses are averaged across bodies if true or not if false (default).

Returns:
