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 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:
• Calculate a resultant vector of the multiple force or moment loads.
• Create a force or moment load on a single vertex with the equivalent resultant vector.
