How do you trim the blank after a forming analysis?
Usually the blank can be trimmed after forming simulation with an
intermediate file – “dynain”. The following is a list of cards needed.
a)       *ELEMENT_TRIM
b)      *DEFINE_CURVE_TRIM – iges curve or line curve
c)      *INTERFACE_SPRINGBACK_DYNA3D to output the mesh after trimming
d)      Specifying the termination to be zero.
