UDF problem about nearest wall !

January 27, 2005, 23:00

Hey:

I have to study particle deposition in a tube with Eulier Model. It needs to incorporate a wall-distance based force term into the convection term.This force term is related to its nearest wall.

I can get the distance by the the Variable C_WALL_DIST(c,t) and get the magnitude of the force term, but how can I finding the _vector_ definition to the nearest wall?

thank you, ALEX

Just wondered how to get wall particle distance (nearest wall) for a 3d dpm calculation?
