Info on turbulentDigitalFilterInlet and turbulentDFSEMInlet BCs for LES simulation

stardust23 · February 26, 2020, 12:50

Dear FOAMers,
I'm running a simple case (boundary layer development on a flat plate) trying to use a LES approach. I have detailed experimental data for the inlet condition and I'd like to test the following 3 BC options:
- turbulentDFSEMInlet
- turbulentDigitalFilterInlet variant=digitalFilter
- turbulentDigitalFilterInlet variant=reducedDigitalFilter

The problem is that, especially for the last two options, there is really few documentation and I'd like to know if some of you has some details about these conditions and how to properly use them.

Thanks in advance!!!

The publications were mentioned in the header files of the BCs I think. Have a look at their .H files, and OpenFOAM Extended Code Guide.
