Hello there !

In order to compute the residual lifetime of air (in a RANS steady-state case of ventilation efficiency), I need to reverse the velocity field (hence what can be called a negative convection).

I'm sure it's doable using UDFs but right know I export velocity data, reverse values under Excel then re-import it under Fluent.

My question is do you see a quicker way to do this in Fluent (no more Excel) or the only way out is to merge an UDF ?


Thanks in advance
