      Yes. You can use the MAPDL commands SECTYPE and SECDATA to change the number of integration points though the thickness in a shell. For example, the following commands could be issued in a Command Object under a “Surface” branch in Mechanical:
      !—-INPUT PARAMETERS—-!
      Thick=2 ! Shell Thickness
      Theta=0 ! Angle (in degrees) of layer element coordinate system with respect to element coordinate system (ESYS)
      Int_Points=3! Number of integration points in layer. 1, 3, 5, 7, or 9 points (default = 3)
      !——–END INPUT———-!

      SECDATA, Thick,,Theta,Int_Points
