impingement information
 
Dear all,

In particle tracking simulation, is it possible to obtain the particle impingement information at wall, such as particle incident angle, particle velocity et al.?

I need the information because I have to impose at the wall a restitution coefficient which is a function of the incident angle. I am currently using CFX 5.7.

Many thanks.

Hi Wenquing,

The variable you want is particle impact angle. See $CFXROOT/etc/VARIABLES for a list of solver variables.

Hi, Robin,

I just noticed that particle impact angle is only available in PTM_UR, but not in CEL. Does this mean I can only use the variable in user fortran subroutine?

Thanks again.

Hi Wenqing,

Yes, currently particle tracking customization must be done through particle user routines.
