Hi, everyone i am modelling a simulation to get reflectance and transmittance plot for air glass interface in 3d for different polarizations of incident wave like TE and TM. but i got stuck at an error while computing in study node, as given below

  • Feature: Stationary Solver 1 (sol1/s1) Division by zero.
    • Function: / Failed to evaluate expression.
    • Expression: abs(comp1.ewfd.port1.Pin/comp1.ewfd.Pmode_1) Failed to evaluate variable.
    • Variable: comp1.ewfd.tEmodex_1
    • Defined as: sqrt(abs(comp1.ewfd.port1.Pin/comp1.ewfd.Pmode_1))*comp1.ewfd.tE0modex_1 Failed to evaluate expression.
    • Expression: nojac(comp1.ewfd.tEmodex_1) Failed to evaluate variable.
    • Variable: comp1.ewfd.PortConstrx
    • Defined as: (1+if((abs(arg(comp1.ewfd.beta_1)unit_rad_cf)<=(0.25pi))||(abs(arg(comp1.ewfd.beta_1)unit_rad_cf)>=(pi0.75)),comp1.ewfd.S1x,0))*nojac(comp1.ewfd.tEmodex_1) Failed to evaluate expression.
    • Expression: comp1.ewfd.tEx-comp1.ewfd.PortConstrx

how to resolve this error?
