Im trying to set up a frequency response analysis with a reduced model (simple acoustic box cavity). But i keep getting this error from the modal solver
- Detail: Undefined value found in the stiffness matrix.
.There are 62273 equations giving NaN/Inf in the matrix rows for the variable mod1.p
. at coordinates: (0,0.05,0), (0,0.025,0), (0,0,0), (0.0317419,0.0350023,0), (0.0158709,0.0425011,0), ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns.
I am new to COMSOL, and there is probably a simple answer, however, I have not been able fo find a good example in the tutorials..
Thank you !
/David
