Normal modes and the thermal loaded prestressed normal models gives same natural frquency ?

Natural frequency for normal modes and the thermally loaded prestressed normal models gives the same natural frequency?

And another issue is I will not be able to proceed directly to the normal modes analysis when it is prestressed with thermal. Solver does not proceed to compute console?

Normal_modes.fem

Pre_thermal_Normal_modal.fem

Hi,

Please take a look in the .out files. The eigen frequencies are different between the two models.
