Still, I cannot get the correct solution due to a Solver Pivot Checking error.<br \/>I tried turning off the Solver Pivot Checking but the deformation is 0. I think my mesh is good except two are very bad (attaching the mesh quality worksheet too).<br \/>I also used the status under contact tool to deal with the bad contacts &amp; over-constraints but there are still a couple of zones with the error, is that what caused the answer to 0?<br \/>I also did this with another similar model but no over-constraints came up but the answer is still 0. I also tried changing the fixed support to the bottom of my carbon plate and then the plate got deformed along the Y axis leading it to look like a loaf of bread. I appreciate any kind of help.
