For the recent version (11.2), there is now an error when the CQUAD4 and orthotropic properties are used, as follows.
*ERROR 1999: Current code for QUAD4 element 1 is incomplete for Orthotropic material properties.
Try a PARAM, QUAD4TYP, MIN4 for an alternate QUAD4 if your elements are nearly rectangular.
Otherwise you will have to use CTRIA3 elements
You can override this and continue with a bdf entry: DEBUG, 248, 1
