Coordinate systems of results
The stress and strain tensors are reported in the global cartesian system unless the option to output results in the part coordinate system has been used. Writing the directional strain tensor is optional in Ansys LS-DYNA: it will only appear in the menu if it is present.
"Extra" data components
The "extra" data components ( SOEn ) are also optional and only appear if present in the database. They are material dependent results, and are treated as scalar data of unknown type by T/HIS.
