Ansys Mechanical Additive Manufacturing error

    • Juan Bu
      Subscriber

      I am trying to run a AM process simulation.This is time sensitive. Need an ansys support engineer. but im getting an error "


       *** ERROR ***                           CP =      40.844   TIME= 12:00:40
       On the AMBU,TIME command, the recoating time value 0 is not valid.  The
       command is ignored.                  "

       

      Here is the  whole solution text
