I am building a CNTFET and have added semiconductor physics module. I want the drain current vs gate voltage. I tried to follow the steps given in the example of MOSFET in the Semiconductor Model Library Model.
When I tried to "get Initial value " in the study I get this error message:

Division by zero.
- Function: /
Failed to evaluate variable.
- Variable: comp1.semi.V_init
- Defined as: ((((comp1.semi.Vth_init*(((comp1.semi.Ndoping_init>=0)*log((comp1.semi.n_init/comp1.semi.ni_init)))+((comp1.semi.Ndoping_init<0)*(-log((comp1.semi.p_init/comp1.semi.ni_init))))))-comp1.semi.chi_init)-(comp1.semi.Eg_init*0.5))+(log((comp1.semi.Nv_init/comp1.semi.Nc_init))*(0.5*comp1.semi.Vth_init)))
Failed to evaluate expression.
- Expression: comp1.semi.V_init
- Feature: Dependent Variables 1 (sol1/v1)


Where exactly can I find the source of this problem?
