I want my analysis to generate a deformation similar to image two, but I haven’t been able to achieve it. I haven’t been able to correctly use the 3-2-1 analysis for the constraints.
What can I do to ensure the deformation is applied correctly?
My boundary conditions are the following:
*Boundary, op=New
*BOUNDARY, Fixed
253, 1, 1
253, 3, 3
*BOUNDARY, Fixed
441, 1, 1
441, 3, 3
*BOUNDARY, Fixed
50, 1, 1
50, 3, 3
*BOUNDARY, Fixed
252, 1, 1
252, 3, 3
Can you share the .inp file ? Or at least a diagram with locations of BCs and load ?

There are no loads, only heat is added that passes in a straight line through the plate and the current restrictions are in the corners
