Thermal Modal Analysis

Hi Everyone,

I would like to launch a thermal modal analysis. Is it possible?

I have added the "eigenvalue" analysis commands to the heat equation

but they might not be compatible... I get the following error:

ERROR:: IterSolve: Failed convergence tolerances.
ERROR:: EigenSolve: Error with DNAUPD, info = -9

and the iterations yield Infinity...

The geometry is a square and the temperatures at the boundaries were defined as constants, all of them with the same value.

How could I do this?

Thanks in advance,

Supituki
