Hello,
I am a new user of comsol multiphysics, currently using multiphysics 5.2.
I wanted to learn about solar cell simulation in multiphysics. I searched and found a youtube tutorial, where multiphysics 4.3a was used.
I believe, I tried to follow all the procedures step by step that was shown.
This message shows when I click "compute" under study in the simulation.
- Feature: Stationary Solver 1 (sol1/s1)
Undefined variable.
- Variable: emw.k0
- Geometry: geom1
- Boundary: 9 Failed to evaluate variable.
- Variable: comp1.ka
- Defined as: emw.k0 Failed to evaluate variable.
- Variable: comp1.kay
- Defined as: (-comp1.ka)*cos(incidenceAngle/unit_rad_cf) Failed to evaluate expression.
- Expression: abs(comp1.kay) Failed to evaluate variable.
- Variable: comp1.ewfd.alphaport_1
- Defined as: j*abs(comp1.kay) Failed to evaluate expression.
- Expression: (-comp1.ewfd.alphaport_1)*j Failed to evaluate expression.
- Expression: comp1.ewfd.intport1((-comp1.ewfd.alphaport_1)*j) Failed to evaluate variable.
- Variable: comp1.ewfd.beta_1
- Defined as: comp1.ewfd.intport1((-comp1.ewfd.alphaport_1)*j)/comp1.ewfd.Area_1 Failed to evaluate expression.
- Expression: abs(arg(comp1.ewfd.beta_1)*unit_rad_cf) Failed to evaluate operator.
- Operator: if
- Global scope Failed to evaluate expression.
- Expression: if((abs(arg(comp1.ewfd.beta_1)unit_rad_cf)<=(0.25pi))||(abs(arg(comp1.ewfd.beta_1)unit_rad_cf)>=(pi0.75)),0,-comp1.ewfd.S1x) Failed to evaluate expression.
- Expression: if(abs(arg(comp1.ewfd.beta_1)unit_rad_cf)<=0.25pi||abs(arg(comp1.ewfd.beta_1)unit_rad_cf)>=0.75pi,0,-comp1.ewfd.S1x)
Will anyone help me to resolve this problem?
Thank you.
