What is right equation?

Please login with a confirmed email address before reporting spam

f  = 1/2εRe( α−β )((∇T · E)/1+ (ωτ)^2)* E − 1/2∇T|E|^2


I wrote Fx "0.5*ε*(alpha-beta)*(-(Tx*Vx+Ty*Vy))*(-Vx)-0.5*ε*(-0.5*α*(Vx)^2+(Vy)^2*Tx) " &
Fy=0.5*ε*(alpha-beta)*(-(Tx*Vx+Ty*Vy))*(-Vy)-0.5*ε*(-0.5*α*(Vx)^2+(Vy)^2*Ty)" in scalar Expressions

Is this right?


How to write right equation for "f" in comsol?
