You can apply multiple forces and pressures. The software superimposes (adds) all pressures, forces, and remote loads.
However, once the gravity or the centrifugal loads are applied, the software does not allow you to add another gravity or centrifugal load.
If you apply remote forces and moments components in more than one direction, for example in X-, Y-, and Z-directions with respect to a local coordinate system, apply all components in one Remote Load definition.
