Applying an eigenfrequency study on a solid mechanics problem in COMSOL 6.1, the eigenfrequencies are returned in a table format using solid.freq. However, I want to index individual eigenfrequencies, in order to perform computations. Example:
solid.freq(1) + solid.freq(2).
However, this indexing method does not work. I tried withsol('sol1, solid.freq, setind(Omega, 1)) but that does not work either.
The parameter required is lambda, and the following works:
withsol('sol1', freq, setind('lambda', 1)).The value of 1 returns the first eigenfrequency.
