how to set the inlet as non-uniform?

egerland · June 22, 2010, 14:48

Hi,
I run my case with a fixed value at the inlet velocity field. Now I want to have an function of the velocity at the inlet. Is there any utility to set the inlet velocity field variable?
Can anybody help me?
Thanx

Hi together,

I would like to simulate a non-uniform flow distribution (swirl) at the inlet of a diffuser. FunkySetFields is already installed on my computer.
Sadly I do not have any idea how to modify the case in order to run the program with a non-uniform flow field.
Does anybody have an advice or a recommendation like a tutorial or an example in order to get an imagination how it works? The “contrib FunkySetFields” in the openfoamwiki is already known.

In advance many thanks

Marc
