Hi, I am trying to simulate a compression of a rubber, which is converging just fine. Afterwards I want to apply pressure on one side, but I get an error message, and quite frankly, I don't have a clue what to do. Any help would be much appreciated...
THE SLAVE SURFACES ASSEMBLY_PACKER-1_CONT_PACKER AND ASSEMBLY_PACKER-1_LOWER_PACKER PAIRED WITH MASTER SURFACE ASSEMBLY_AXD Packer Support lower-1_PACKER_CONT_LOWER INTERSECT EACH OTHER. IF BOTH PAIRS ARE *CONTACT PAIRs, THESE TWO PAIRS SHOULD NOT BE SIMULTANEOUSLY PRESENT IN A STEP BECAUSE OF POSSIBLE CONVERGENCE PROBLEMS; USE *MODEL CHANGE,TYPE=CONTACT PAIR TO REMOVE ONE OF THEM. IF BOTH ARE *TIE PAIRS, THE REDUNDANT TIES WILL BE REMOVED AUTOMATICALLY. IF ONE PAIR IS *TIE AND ANOTHER IS *CONTACT PAIR, REMOVE ONE OF THEM.
So far I have created a step after initial loading with the fluid pressure, and the initial loading inactive. I have created a surface pair and applied pressure penetration in this step. Also, I have fixed the initial movement at the "new" location. Still, I get non-convergence after 15% analysis time in secondary step...
