Problem with Interpolation (Comsol 5.3a)

Please login with a confirmed email address before reporting spam

Dear all,

this simulation model interpolates a data from a file which plots refractive index and voltage. It is able to import the file but when I start to run the model, it fails. I think there is a problem with defining the units/function in the interpolation section.

The error says: Circular variable dependency detected. - Variable: comp1.mat5.rfi.n_iso - Geometry: geom1 - Domains: 3, 5

Can anyone help me figure out the problem?

Kind regards, Grace

Hi Yolanda,

I think you appended wrong file.

Anyway, the error message indicates that the refractive index in the material with tag 'mat5' depends on its own value.

Hi,

it seems like the file is too big to be uploaded. I don't quite understand what you mean by 'depends on its own value'. Could you please explain what you mean by it?

Kind regards, Grace
