Dear Foamers,


Is there a way to set that every particle passing through a specified location is arbitrarily experiencing a slowing down ?

For instance, in a langrangian solver, I would like that every particle passing through Y€[-0.1;0.1] experiences a kinetic energy loss of 0.1%/mm.

Is there a way to define a rule to do so ?


Cheers
