To verify my comsol results, I evaluated a round solid aluminum beam with the following specifications and load case:
beam diameter: 28mm beam length: 300mm
Physics: The beam is extruded in the z-direction Fixed Constraint: on the bottom face (3) Boundary Load: on the top face (4) of 1000N
Running a Stationary Study, I receive the following outputs: Volume Maximum Total Displacement (mm): 0.2741
I have verified this result against Fusion 360's NASTRAN solver and the analytical solution, both of which give me the following result: Total Deflection: 4.32mm
Am I overlooking something or is COMSOL outputting very wrong values?
