Hello,

I want to define initial gap opening to be zero instead of the default value 0.002 but I don't know how to use the <<*SECTION CONTROLS, INITIAL GAP OPENING>>. Should I define it in material or in step? And should I write <<*SECTION CONTROLS, INITIAL GAP OPENING=0>> or the 0 must be in a separate line? I tried both but it didn't work. Please help me to solve this problem. Thank you
