Contact in SOL 101

Contact in SOL 101

(OP)
I'm running a contact analysis in SOL 101.

My mesh of master and slave contact edges is not a confirmal mesh (i.e. the nodes of master and slave edges / region do not coincide.

In that case, is it a good practice to define two contact pairs ? That is : one pair slecting region 1 as source and region 2 as target and then another pair with source and target sapped (i.e. region 1 as target and region 2 as source).

Is this a good practise?

Or, will it make the problem over-constrained? I guess it would suit the purpose as it would create a symmetrical contact.

Thanks.

Can anyone please help/advise? I look forward to your replies

RE: Contact in SOL 101

Hello!,
Not at all, you don't need to repeat the regions, select the source region as the one with smaller size and more refined mesh, and the target region with the bigger size, and create only ONE connector per pair of regions. Repeating element faces multiple times in the same or different regions can significantly increase memory requirements and degrade performance.
Best regards,
Blas.
