Hi,

I implemented already an Additional Variable under the form of a Transport equation. I didn´t get good results and I would like to have full control on the implemented transport equation.
The problem is essentially the presence of the diffusive term in the equation provided by Ansys CFX (I don´t need it) and the presence of the volume fraction in the formulation of each term.

For this reason I decided to implement a new variable linked to User_CEL. Inside the routine then, linearize the system and solve it iteratively.

I would like to receive some information regarding the following aspect:

1) Once obtained a linear equations system I want to solve in an iterative way.
Did someone tried this before in a USER_CEL? Do you have an example of it?

Thank you in advance,

Filippo
