Excessive deformation in flow forming process 3

[Push123456]

I am doing explicit dynamic analysis of flow forming process which comprises of reducing hollow tube/solid cylinder's outer diameter using one or more rigid rollers. In that I have fixed bottom nodes of the cylinder and roller is given feed and rotational velocity around the cylinder so that the roller travels a helical path around the workpiece.

I am getting excessive deformation of the workpiece. How to avoid that? Which is the best contact interaction to be used in this type of simulation?

I am attaching my input file for the reference.
Thanks

100Sec is too large to use xpl. Try std, contact pair, surface to surface, finite slide contact.

Thanks abqMaster for the suggestion, but I have to use explicit because it takes less time for solving the problem.............Can you please tell me how to reduce excessive deformation in this problem?

If you are facing excessive element distortion problem, you can try ALE adaptive meshing.
