Demo for multi-step operation by using the "dynain" file: step1: Save the parts to be used in second step by defining: *INTERFACE_SPRINGBACK_LSDYNA 99 *SET_PART 99 1,2 $ This will generate a "dynain" file, which includes nodal coordinates and element connectivity with initial stresses for the 2nd step operation. step2: rename the "dynain" file as "dynain.k" and incldue it in the 2nd step input deck Download the step1.k and step2.k for exercises.
