Unit normal vector of nearest wall

l_r_mcglashan · August 3, 2009, 06:17

Hello,

I'm looking to implement a wall lubrication force for multiphase flow. For this I need the unit vector normal of the nearest wall.

I found reflectionVector, and that gives the unit vector normal at the wall. Is there a function to give the unit vector normal of the nearest wall?

Yes, this is precisely what you need.

It is used in wall reflection terms in Reynolds stress transport turbulence models.

Enjoy,

Hrv

Ah, wallDistReflection! I somehow missed the fact that it inherits from reflectionVector in the class reference. Thank you for the gentle nudge in the right direction.
