Warp Angle (FEM mode)
Warp Angle is a way to measure how far is a quadrilateral element from being planar. When you check your mesh, Creo Simulate uses the Warp Angle quality measures to highlight elements exceeding the maximum warp angle.
Creo Simulate calculates warp angle, W, according to the following formula:
W = arc sin (h/e)
where h is the distance between the nodes and the reference plane, ande is the shortest edge.
