Hello everybody,

I need some help to clear my mind. My purpose is to adapt the chtMultiRegionSimpleFoam solver for multispecies case.

- So I started by adding 3 scalar transport equations,...

Hi,

My scalars transport equations are now working well. I didn't add the max and min function. Now I will have a look at the rho/Cp/lambda/mu state equations.

Thank you again.

I have added the density inside all my term of the equation. It still computes and the scalar is still unbounded.

The Y1Eqn.H files :

{
for (label i=0; i>scalar1Fluid.size(),i++)
{
solve...

Thank you Marupio. It was a problem with the prtList. It seems it's working now, I just have a problem of dimension conflict.

Edit :
I might need your help again.

The equation I'm solving is...

I'm still on it. I have a problem to declare the diffusivity of the scalar.

In a multiregion solver, the createFluidFields.H file is a loop on each fluid region and the variables are defined as...

I have added 3 transport equations in the chtMultiRegionSimpleFoam solver.

I defined scalar[i]Fluid, i = 1, 2 or 3 as a ptrList<volScalarField>

Then I define scalar[i]Fluid[j] , j= number of...

Transport equation in chtMultiRegionSimpleFoam solver

Hello everybody,

First of all, I am a new user of OpenFoam.

I need to develop a scalar transport equation (which would be mass fraction) in the chtMultiRegionSimpleFoam solver in order to...
