Hello Foamers,
Hope that all is good with you people amid this situation. My problem might be very basic to some people but I'm facing some issues while troubleshooting this. The problem is as :-

I m using some set of velocity datas collected at every 0.5 time step(setting up in constant/boundaryData) as my timeVaryingMappedField at the inlet of my domain and I m wishing to use some kind of wall-function for this simulation. While using the Spalding wall function and setting the required b.c in the nut file I m getting some abnormal Courant number at some midway of my simulation. I ran the same simulation without wall function and it was running perfect but the aim is to run with the wall function. The nut file is shown below and I believe the b.c condition at the inlet might be something else.

Will be really helpful if anyone can provide some solution for this problem.
