Respected Faculty

Please suggest, what is syntax error in this objective function for heat transfer through radial object ? I am using Comsol multiphysics version 6.0

(1-q)*comp1.intop1(k_simp*ht.gradTmag^2)+q*h0*hmax_design/A*comp1.intop1(sqrt(d(comp1.dtopo1.theta,x)^2+d(comp1.dtopo1.theta,y)^2)^2

Thank you sir

There is at least one missing right parenthesis at the end.

I would say the closing bracket ) of sqrt is missing.

(1-q)*

comp1.intop1(k_simp*ht.gradTmag^2)

+q*h0*

hmax_design/A*

comp1.intop1(

sqrt( d(comp1.dtopo1.theta,x)^2

+d(comp1.dtopo1.theta,y)^2

)^2

Just add another ) to the end )^2 which would be

))^2

Nice Greetings
