Dear everybody,
I want to simulate the wind flows around a building using LES. This is a 3D problem. To Inlet boundary , I want to use inflow turbulence.
Velocity or temperature change with both position and time.
I have huge experiment datas of inflow boundary, change with z , y, and time. In unsteady simulation, in every time step , I want to read these experiment data as the inflow boundary condition, if this can be realized easily in OpenFOAM ? Thank you .

Does that mean you know how to work with TimeVaryingMappedFixedValue or are still searching for a solution?

I am a newer of OpenFOAM, I'm still searching for a solution,I begin to look TimeVaryingMappedFixedValue, but it seems to be difficult.

This may be. Especially as a beginner.
Just tell us what you don't understand and maybe we can help.
