Best Practices–Loads in Creo Ansys Simulation
Multiple loads applied to the same reference are considered cumulative and are calculated in an additive manner. The only exception is when using a single vertex as a reference as described below:
Application of multiple forces or moment loads on a single vertex, while being a theoretically valid scenario, is not supported by the simulation solver. In case there is a need to analyze such a scenario, use the following recommended workaround:
1. Calculate a resultant vector of the multiple force or moment loads.
2. Create a force or moment load on a single vertex with the equivalent resultant vector.
