Kobology 0 Report post Posted July 25, 2016 (edited) Hi there, I'd like to set up a test simulation, where the green cylinder moves with a certain speed down (-Y) on the blue block. I can't find the right way to set up the contact between the two bodies. In my case they don't get in contact an any time, the cylinder just fall through the block, although the cylinder should force the block to a deformation and don't move further. Can somebody please tell me the right cards for concact type and entity set types (master and slave)?? MY SET UP at the moment: PFBODY: cylinder, block with nmodes=10, Craig-Bampton Ground: some nodes (for the 4 FIX an the one TRANS joint) Concact: interfaces panel type: MBCNTDS master set: outer grid nodes of the cylinder as SET_GRID card image slave set: block top nodes as MBDSRF card image My goal in this test is a topology optimization of the blue block.

Guest Report post Posted July 27, 2016 Hi, In the model, are both the components flexible? Then you are using the right contact interface type. But you need to create a MBDSRF (multi body surface) for using Multi body contact for deformable surfaces. Go to Entity sets>> Create an element set with slave elements. use this set to create contact interface and try again. Quote Share this post Link to post Share on other sites
Kobology 0 Report post Posted July 27, 2016 Thanks for your reply. Actually I create the slave entity set as a MBDSRF, like said in the Bulk Data Entry of a MBCNTDS (for the SRFID of it). I attach the .fem file. Regards cyl_on_block.fem Quote Share this post Link to post Share on other sites
