diffuseBndry

DiffuseBndry

Works with VSimBase, VSimEM, VSimPD, VSimPA, and VSimMD licenses.

This particle sink reflects particles with velocity taken from thermal distribution.

diffuseBndry Parameters

minDim (integer): Minimum dimensionality for which this sink is applicable (1, 2, or 3).

lowerBounds (integer vector): Gives lower bounds of the particle sink in cell indices.

upperBounds (integer vector): Gives upper bounds of the particle sink in cell indices.

direction (double vector): Inward normal from the reflecting surface.

surface (string): Physical location of the reflecting surface.

vsig (double vector): Thermal velocities at the boundary.

acc (float): The thermal accommodation coefficient.

useObliqueReflection (integer): A flag, if set sink will work with oblique boundaries.
