Prestress Modal Analysis Overview
Use results from a static analysis to calculate the natural frequencies and mode shapes of your model.
For example, in rotating machinery, such as a turbine blade, you may want to run a prestress modal analysis after a static analysis to get more detailed information about the applied loads and the stiffening and weakening of those loads.
See Units of Modal Frequency Results to find out how Creo Simulate reports frequency results.
See Spin Softening to find out how Creo Simulate automatically compensates for the effect of relative motions that can occur during prestress modal analyses when a centrifugal load is present.
