Nettet5. jun. 2024 · Thus, the Harmonic Perturbation tag should not be used for the loads in this case, unless you change the Linearity setting. When you add a Frequency Domain, Prestressed study, the frequency response study step is set up for perturbation analysis. If the study is of a mode superposition type, then the study is always of a linear … NettetThis control is provided for convenience of load generation for linear perturbation analysis. In general, a new set of loads is required for a linear perturbation analysis. This key controls all mechanical loads; it does not affect non-mechanical loads. Non-mechanical loads (including thermal loads) are always kept (i.e., not deleted).
