ST7-1.70.60.4 Combining Harmonic Response and Linear Static Results
As the assumption of linearity is inherent in both the linear static and harmonic response solvers, the principle of superposition is applicable to results generated by each. However, because the harmonic response solver may produce an envelope of un-equilibrated results (depending on the method used to combine the modal responses), whilst the linear static solver always produces equilibrated results, the superposition of these two types of solutions is not always straightforward.
This Webnote presents two methods of generating results from the combination of static and harmonic loads.
