I am new to IFM programming ... Does anyone have an idea how to implement the competitive Langmuir isotherm in Feflow via IFM-Plugin or dealt with a similar problem? At equilibrium the competitive Langmuir isotherm describes the concentration at the solid phase for two species in the following form:

[b]Cs(species 1) = k1*Cf(species 1)/(1+k2*Cf(species 1)+ k3*Cf(species 2))
Cs(species 2) = k4*Cf(species 2)/(1+k2*Cf(species 1)+ k3*Cf(species 2))
[/b]
with k1 to k4 being the parameters of the Langmuir isotherm and Cs and Cf being the concentrations in the solid and in the fluid phase, respectively.

Thanks a lot for your help and best regards.
