Hello all,
I am using ANSYS classic for structure analysis.I have two load steps and I need to define the element coordinate systems for selected elements ( in 2nd load step) aligned with principal stress directions obtained from 1st load step.
Earlier I did this in workbench and there I was extracting the principal stress vector data for 'elemental mean' (shown in attached figure) and then in 2nd load step creating the local coordinate system using THXY, THYZ and THZX data. Then assigning this local coordinate systems to appropriate elements.
