MAPDL Error on Radius/Thickness Ratio — Lesson 8

Why does MAPDL show an error message about the radius/thickness ratio?

The reason for this error seems caused by very warping elements. The shell element radius to thickness ratio check is not controlled via the SHPP command. This is a message that is not part of the element shape-checking logic, so the SHPP command will have no effect on its behavior. The workaround is to modify those shell elements until they meet the requirement or check the warping quality.
