Dear Foamers,

I want to implement a transient boundary conditions (time depended inlet (p,U and T come from a real test) )

I'm using timeVaryingUniformFixedValue but i don't see how to define my internalField (uniform, nonuniform or what?)


Any idea please?!


Best regards.

Hi,

you can do both.

It is possible to start the calculation with uniform initial fields. But another good procedure is to start the transient calculation from the results of a stationary calculation, so you have nonuniform intital fields.

The transient BC timeVaryingUniformFixedValue means that at this BC the values will be <uniform> so no parabolic shape or similar.
As for your internalField that does not matter so much because it will be adjusted according to your BC's during the simulation.
Hope I've unswered your question.
Ciao
