Contact - avoiding separation

Contact - avoiding separation

Contact - avoiding separation

(OP)
Hi,
I am performing a contact analysis using MSC Marc 2010 and Patran 2010. During the analysis, as I look the .log file I can see a large number of messages “recycling increment due to separation”. As separation results in additional iterations (which leads to higher costs), I would like to know how can I better configure analysis parameter to avoid separation. Any idea?

Thank you

RE: Contact - avoiding separation

(OP)
The parameters that I can control are the distance tolerance of the contact detection and the separation force/stress (that I think is more relevant, but I’m afraid of lose accuracy in the solution). Would you recomend any value?
Can other parameters, like time steps make any difference in the contact behavior?
Thank you!

Yes, I'm taking a look in some tutorials and other files...

Tks
