For each coordinate direction, you can select if a force or a displacement should be entered. For example, if a calculation of a tapered roller bearing should be done considering only radial load, the displacement in axial direction can be fixed to zero and the reaction force in axial direction will be calculated.
A moment load or a rotation (misalignment) can be entered for two directions only, because the rotation around the bearing axis is not constrained.
Use the radio buttons to select the elements you want to enter.
