Comsol wgm eigenfrequency
WebEigenfrequency. The Eigenfrequency () study and study step are used to compute eigenmodes and eigenfrequencies of a linear or linearized model. For example, in electromagnetics, the eigenfrequencies correspond to the resonant frequencies and the eigenmodes correspond to the normalized electromagnetic field at the eigenfrequencies. WebDec 6, 2024 · Depend on Study, for expl. if it Eigenfrequency you set up a number of eigenfrequency and frequency for finding around if you know. If last frequency is 0, COMSOL start finding from 0Hz.
