1.	/MAT/RIGID is not compatible with kinematic condition or with Advanced Mass Scaling (/AMS), but it is compatible with /BCS.

2.	/MAT/RIGID is not compatible with /PLOAD, /CLOAD, /GRAV, /IMPDISP, /IMPVEL, /IMPACC, /IMPTEMP, /INIVEL and /INITEMP. If loading is used, it is recommended to use /RBODY, instead of /MAT/RIGID.
