NonUniform Velocity Inlet
I'm trying to perform a steady state simulation (simpleFoam) to analyze the airflow around a sailing boat. In order to validate my results I'm comparing them with the ones coming form a measurement in a wind tunnel. I have the velocity profile of the wind tunnel which is not uniform, and I wold like to implement it as a boundary condition ( it means I have to set precise values of velocity at specified heights).
I found, in the PitzDailyExptInt tutorial, the type: timeVaryingMappedFixedValue for the inlet (Folder 0/U).
I have set (constant/boudaryData/inlet/0/U) the velocity values
I have set (constant/boudaryData/inlet/points) the points coordinates corresponding to the velocity values.
The problem is that I don't get a correct velocity profile! I think the problem is related to the average velocity value I have to set in constant/boudaryData/inlet/0/U
I don't think I have well understood how this utility works...does anybody knows how to help me?
I have also tried to implement the non uniform velocity profile using the type: value nonuniform List<vector>
But in this case how can I associate the velocity value with the space coordinates?
