Vector Principal Stress Command in Mechanical APDL ?
I need to obtain Principal Stress Orientations( i.e. Euler Angles rotXY,rotYZ,rotZX at the element centroids) so that I can rotate each element coordinate system according to Principal Directions.
In the Mechanical it can be done via exporting Vector Principal Stresses. However, I want to do this in APDL to automate the process. I couldn't see any command related to Vector Principal Stresses in the Mechanical APDL Guide.
Anyone know which command in APDL would work ?
