Parametric Study making functions

Hi there,

I am doing a parametric study with a variable T_initial for a frequency domain simulation for a fixed range of frequencies, this worked well

I need now to change the set of frequencies with a function freq_range(T_initial). In the study frequency-domain it always says failed to evaluated the function. The function was defined in the global definitions and it is plotted well in the results.


The field frequencies does not accept my function I dont know why.
