kikko is on a distinguished road
Good morning,
I want to use the ORourke collision model for my simulation but I have see that I can set only 0 or 1 for the the coalescence it true???
if I set 1 all the particle coalesce and the diameter became too big...
If I set 0 no particle coalescence...
Open Foam don't permit me to set an intermediate value.
Does exist an intermediate case???
Is there another parameter to set for the coalescence????
Thank all for attention

coalescence is not a scalar, it is a boolean.
it is a flag you set if you want to allow parcels to coalesce or not.

so either you have coalescence true or false, 'intermediate' values makes no sense.
