Adding momentum source term to BC Fluid Interface Boundary Condition
 

Hi everyone,


I want to add momentum source term to BC Fluid Interface Boundary Condition. So, i have changed line in CFVMFlowSolverBase.inl line: 1441 - Version: SU2-7.3.1.


for (iVar = 0; iVar < nVar; iVar++)
{
Residual[iVar] += weight * (residual[iVar] + tmp_residual(iVar]);

}


where tmp_residual stores my source term.

However, no matter how large i set the source term, nothing changes in the flow field. Am i doing something wrong or is my source term not dominant enough?

That should be correct, have you tried comparing your source term with the normal residual?
