PARAM, EDGESTR

Bulk Data Entry This parameter is a switch for the type of Grid Point Stress calculation for mid-edge nodes in second order elements.

Parameter Values Description
EDGESTR <ELEM, NODE>
ELEM (Default)
An improved method for grid point stress calculation is activated. The stress at the edge is calculated from elemental corner stress first, and then averaged between connected elements. The grid point stress at the edge might be greater than the stresses at the corners.
NODE
This is the old method. The grid point stress at the edge is calculated directly by averaging the grid point stresses at the corners.
