  I am trying to create a new material properties of anisotropic CFRP from the GUI, not from using codes. But it keeps rejecting it and keeps giving messages of ignore commands. I am using the student version ANSYS 2022 also im doing these in APDL.

  This appears to be an MAPDL GUI bug.
  The TBOPT field is not used for the ANISO material option.
  As a workaround, try defining your material directly with commands as follows:
  *************
  MP,EX,1,39600
  MP,EY,1,3065.9
  MP,EZ,1,3065.9
  MP,PRXY,1,0.2
  MP,PRYZ,1,0.3
  MP,PRXZ,1,0.2
  MP,GXY,1,2075.1
  MP,GYZ,1,1179.2
  MP,GXZ,1,2075.1
  !
  TB,ANISO,1
  TBDATA,1,643.5,8.860588,8.860588,0,0,0
  TBDATA,7,13.2,13.2,13.2,0,0,0
  TBDATA,13,6.93,6.93,6.93,0,0,0
  **********
  After you define the materials just use MPLIST and TBLIST commands to check your inputs.
  Don't use the MAPDL GUI for this material combination.
