      Hey,

      I'm trying to model a laminate using REINF265, with the below code:


      FINISH

      /CLEAR

      /PREP7

       

      !EPOXY

      MP,EX,1,3.78E9

      MP,EY,2,6E9

      MP,EZ,2,6E9

      ESEL,ALL

      EREINF


      when EREINF is issued, it gives a warning that "no new reinforcing elements are created with the last EREINF command, please verify your model carefully"
      can anyone please state what is wrong with this code??

      best regards,

      Hi Zaid,

      This is a warning message. After the EREINF command executes, you can issue ETLISTELIST, and EPLOT commands to verify the newly created reinforcing element types and elements.
