How to define a contact between parts
Hello,
to define a non-linear contact, you need to define two sets or contactsurfs, a so called MASTER and SLAVE surface / set. These sets are then combined into a contact formulation in which you can define penalties, friction and further parameters. A contact of type SLIDE will only allow for pressures to be transferred between the surfaces / sets. The FREEZE and TIE types will also transfer tension.
There is a tutorial on the training center, describing the process:

Further tutorial is in the online help of HyperWorks / OptiStruct.

Dear Rahul Ponginan,
I do contact simulation of two deformable parts in RADIOS Block (INTER_TYPE7 penalty). One part does not move while the other one does. Surface of two parts is not flat so contacted areas are changed during simulation. Two parts have the same mesh size and the same mechanical properties. I tried 2 cases: 1) the fixed part is the master and 2) the moved part is the master. The resultant contact force in case 1 is 3-4 times larger than the one of case 2. Could you please give me an advice, which part should be the master? Should I impose 2 cases of contact at the same time? And why are the resultant contact forces too much different?
Thank you!
Best regards,
Huynh
Huynh,
Assuming both are same material, make the finer mesh as master and coarser mesh as slave.
