Contact Analysis with MSC.Marc
(OP)
Hi,
I would like to get some advices from experts in this group. I used to work with Abaqus and this is my first experience with MSC.Marc. I got following error and I am wondering how can avoid this error?
--------------------------------------------------------
recycling increment due to body to body contact
maximum recycles reached but iterative penetration procedure not complete
increment will be recycled
increment cut-back number 8
*** note - initial stiffness contribution turned off in an
attempt to improve convergence
*** error - unable to reduce time step below minimum of 1.00000E-05
specified in input last cut due to number of recycles too large
-----------------------------------------------------------
Thank you,
AAY

RE: Contact Analysis with MSC.Marc
You could try to modify the parameters of the non-linear analysis (such as the time-step, the residual error etc.) and look what's happen.
I had similar problems but I cannot tell you more because I'm still fighting with them.

By the way, I found an online document. It may be helpful for you.
