  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 ETLIST, ELIST, and EPLOT commands to verify the newly created reinforcing element types and elements.
