refValue for directionMixed bc

remi · April 24, 2009, 11:53

Hi everybody!

I'm using a directionMixed boudary condition on velocity at the inlet of a simple 2D channel.
I would like to set the X (normal) component to fixedValue and the others to zeroGradient.
Knowing that the refValue is a symmetrical tensor, how should i set the six components, and what do they mean?

Thank you for any help, have a good day!
