I downloaded this square2D.fsp from this bandstructure page. I tried to change the f1 and f2 parameters in the dipole_cloud analysis group. However, there is no effect at all, even though I have hit the OK button. When I open the analysis group again, the parameters stay unchanged, the frequency of the dipole sources are not changed. What is the reason?
there are some parameters set in “model”. you can modify there.
I’d like to suggest another candidate approach to modify the frequency(f1,f2) variables in the analysis group. You can additionaly type f1, f2 variables - f1 = 10e12; f2 = 700e12; - as you want to assign in the starting line of the setup script, then click OK.
If you take a close look at one of the dipole source S1 of dipole_cloud analysis group in the objects tree, you can find out the start, stop frequencies (f1,f2) have been changed as you want.
I think @gsun’s reply is the reason why the parameters (f1, f2, and more) stay unchanged, it is because that there is a higher hierarchy - Model that is setting the those parameters. So the analysis group will look for what is pre-set in Model. Now, changing these parameters in Model are going to be effective and in fact this can be a very useful feature if you need to change the same parameter in multiple groups/objects.
The suggestion from @isawjsy is going to be effective too and I think this will override the pre-set hierarchy. I would suggest users pay extra care when using this approach.
