Hello,Foamers.
I am using the openfoam 2.4.0, and trying to write a new solver which is similar to chtMultiRegionFoam , here are my problems.
First, I need to solve equations in the entire domain both in the fluid part and solid part, and I want this equation to be discretized into only one matrix A, in which the interface between fluid and solid need not to be treated as boundary.
Second, solve the equations in the fluid part. Some calculated result in the first step needed to be transferred to this step as the energy source, but only in the fluid part .
How to implement this? Can anyone give me some advice? Thanks a lot.
