Respected Sir,
I am working on chemical vapor deposition using transport of dilute species module.In the"flux" boundary condition i wanted to enter a non-linear rate expression--0.01*((c2)^0.5)*c where c and c2 are concentrations of two compounds A and B.When i am executing this it is showing the following error
Attempt to evaluate negative power of zero.
- Function: ^
Failed to evaluate expression.
- Expression: d(d((0.01*mod1.c2^0.5*mod1.c*test(mod1.c))*(dvol),{test@0}),mod1.c2).
I kindly request you to help me as how to enter non linear rate expressions in the transport of dilute species.
Thanx a lot
Yours sincerly

Does sqrt(c/C0)*c2 work? C0 would be the standard concentration 1 mol/L which you have to define in the parameters list.

I will try sir but what about powers other than 0.5.Most non linear rate expressions have powers other than 0.5 too.Plz help me out sir...
