Contact Analysis with MSC.Marc

[feajob]

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

Well, as far as I know, this is a problem of convergence.
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.

Solidal Catibon.;-)

Hi Catibon, thanks for your reply. You are right, I fixed my previous problem it was related to the time-step parameters. Now, I have another problem. In .stderr file, I got "Address Error". I have to fight with this one now!

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