Could sb please guide me about how ABAQUS sends the LFLAG to UELs?
I have a UEL for crack propagation which goes through assembly process when LFLAGS(3)=1. My original coding was for a horizontal crack. When I have a vertical crack, I noticed that LFLAGS(3)=4 is transferred to the UEL. But I cant understand how this is happening.
I would greatly appreciate your advice.
