Hi all, I am running ABAQUS/Explicit incremental metal forming simulation. The tool radius=3mm, blank mesh=0.5mm, blank thickness 0.8mm, shell S4 element, friction=0 now. tool speed up 20 times faster than experiment, with mass scaling to target 5E-6. time scaling factor=0.7. damping alpha=10.
However, the simulation stops automatically with the following error:
Excessive incremental rotation of the elements in element set ErrElemExcessIncrementalRotation-Step1.
There is only one element with excessive rotations
Anyone has ideas? Thanks!
