Failed to evaluate variable.

Please login with a confirmed email address before reporting spam

Hello

I am a beginner in COMSOL 4.0

I have tried to build a model just like the model "periodic_boundary_condition"

So I started a new model and added everything that is in that model, I perfectly

iterate what is there...Then when trying to compute the study, this error occurs:

Failed to evaluate expression.
- Expression: d((-j*mod1.emw.omega*sqrt(epsilon0 const*mu0.....
Failed to evaluate variable.
- Variable: mod1.emw.murScalar
- Defined as: (((((mod1.emw.murzy*mod1.emw.nz)+((mod1.emw.murxy*mod1.emw.nx)+....
Failed to evaluate variable.
- Variable: mod1.emw.murzy

I think the problem is in some of the variables but I just iterated everything in that model

and (for your information) that model worked well and I computed the study there without any problem.


So what is wrong ?
