I am not familiar with what you are trying to do, so maybe someone else will comment. But, just make sure you understand, the thermal loading applied would be sinusoidal in nature, as that is what frequency response is doing. Also, the point load would be sinusoidal. It can be a unit load, but it will oscillate at the user-defined excitation frequencies.
