How can a simply supported boundary condition be defined in a solid model?
For example in the beam model, one can specify the following boundary condition at both the ends of a slender circular bar:
Ux = Uy = Uz = 0 ;
Rx = Ry = Rz = free
If a solid model is used instead of a beam model, applying Ux = Uy = Uz = 0 at the end faces would also arrest rotational degrees of freedom on those faces and it would act as a fixed boundary condition.
So how can a simply supported condition be applied in the solid model?
