My task is to compare my model with the test data. I have 6 plates whose dof I can control by using general constraint. In these 6 plates for now 5 are completely constrained. One of them is constrained only in (Z, Rx, Ry, Rz), so the plate is free to move in (X, Y). In that plate, I am applying enforced motion (ACCE) in X and Y direction. That scenario does not converge.
I also tried freeing all the dofs (X, Y, Z, Rx, Ry, Rz) and apply enforce motion (ACCE) in (X, Y, Z) but again it diverges.
However, when I contrain (X, Z, Rx, Ry, Rz) and keep (Y) free and apply enforced motion (ACCE) in Y direction, the solution converges.
I have also pointed out the origin of the axis direction. Both the plate, force and origin has the axis direction.
It's really hard to say what the issue is without reviewing the model. I would recommend using a local coordinate system so the acceleration can be applied in only one direction.
