I'm trying to run a model that contains beam and solid elements. I've greatly simplified what I'm actually analyzing to figure out why my contact sets between a beam and a solid are not working.
I have a large beam cylindrical beam standing vertically and is fixed on it's bottom joint. I have a plate constrained to the cylindrical face of the beam via contact set (it's also constrained in the model). It meshes completety fine.
When I click solve, I get an error that says: "Model is unstable. Check that you have applied adequate fixtures to stabilize the model"
I don't understand why. The only part that has a fixture is the beam. The plate is bonded to the beam and cantilevering out from the cylindrical face. Why isn't the bonded contact set creating a "weld or adhesion" that makes the solid and beam move together?
