Hello all!

I would like to impose a velocity profile at the inflow boundary. My velocity profile is in the form of discrete values of the velocity magnitude at specific x, y, and z locations. What is the best way to impose this BC in OF 1.4.1?

Thanks for your time.

Joe

Have a look at timeVaryingMappedFixedValue b.c. which interpolates in space and time.

Hi,

does anyone know of a easy way to create those needed boundary field values from experimental data? I would like to impose a 2D velocity profile at the inlet, which are available in VTK format (some other format would be available as well by exporting the fields using visit).
