My problem is simple : I made a UDF to define my injection, it works but I would like FLUENT to inject only one particle in each parcel and not 40 particles or, worse, 0.12 particle.....It would be much easier for me to follow my particles' trajectory if there is only one particle by parcel. Does somebody know how can I do ? Is that possible to put a variable particle time step ? Thanks for your replies, pauline
