Hello everyone


I want to model a special kind of diffusion with Ansys Fluent where one of the governing differential equations has a structure which is not very common, hence I can't use any of the provided model's equations as a surrogate.


The equation looks as follows:

m_11 is the governing variable with it's time evolution playing a crucial part in the model. J_s is the diffusion flux, which will be model via the dilute approximation (hopefully) regarding species transport. Additionally, m_11 is included in one of the other equations, for completeness sake here they are:

and

My question is the following: Can I implement a non-linear partial differential equation via an UDF with one of the inputs, J_s, being the diffusion flux calculated by Fluent via the dilute approximation?


Thanks in advance,
