i have a problem in my project. I use v.4.2 and AC/DC module in frequency domain.
I have a model built by some materials, that they depend of the frequency (electrical conductivity, relative permittivity) .
I would like to built a function to inteporlate the values in frequency and then to make a parametric sweep on frequency values.
For example:
In material --> new material --> functions --> interpolation
Function name: a
t f(t)
1 10
2 20
3 30
....
In study --> Parametric sweep: f= range (10,10,100)
It is corrects?
I have an error: 'Failed to evaluate variable' .
How can I define the function?
Thank you so much for your help!
Chiara

Alexander, above has already answered your question.
1. Go to parameters, input a parameter name, say "param" and define it a "0" value.
2. Go to function, interpolation, define data as appropriate, let us say the function name is "int1".
3. In the parameter sweep, select "param" and then define a range, i.e. range(0,10,100). Note that the range is the first column of your interpolation table, in other words, it is the independent variable or x-axis terms.
4. Now you want to apply the above function, for whatever purpose, say as a boundary condition. In that case, just type int1(param) on a given boundary - this is essentially your y-data for a given x-data (defined by "param").
