Hi,

I got this error
Circular variable dependency detected.
- Variable: mod1.icp.sigmazz
- Geometry: 1
- Domain: 2 3 5
Whot it is mean ?

Variable sigma have defined in material browser.

Thank very much.

Hi

a circular dependency means that you have defined an input variable on some results or output variables.
This happens when you set up very non-linear models, but also often when you happen to use a variable name that COMSOL already has defined internally.

You need to go down the chain from your "sigma" definition and check how its defined and if some of the variables might have a name conflict with COMSOL internal variables names

Good luck
