Hi leflix,

I don't want to use the outlet of A as inlet of B. As you can see from the picture, the outlet of A is far downstream from the inlet of B, which is "in the middle" of A. This is done to...

I agree: as a matter of fact, I'm prescribing p0, T0 and flow angles at B's inlet (interpolated from A's solution) precisely for this reason, i.e., because in compressible flow prescribing velocity...

I wasn't thinking about using LES, just copying that type of strategy, i.e., impose a BC somewhere, and iteratively adjust the imposed values to match some values somewhere else.

But let's leave...

Ciao, Filippo,

thank you very much for the answer.
1. yes, the formulation is the same, even though the code is different. In both domains, RANS equations are solved.
2. the outlet BC of A is a...

Getting inflow conditions for a simulation from another simulation

Hi,

I need to solve the flow in a interior domain B (for example flow around an airfoil inside a non-constant section channel), and the inlet flow is not known, but must be extracted by the...
