Hi,
I am trying to do lattice optimization on a simple block with structural boundary conditions. I keep getting Error #312 with the explanation below:
In static load case 1
the compliance is negative or large -5.91187e+17.
Optimization/buckling analysis cannot be performed.
due to possible rigid body mode.
I tried constraining different dofs but it did no good. would really appreciate any help regarding this issue. Attached you can find the model. Thanks!
