Default Plane, which traps particules but don't alter flow

Hallo,

I would like to create a plane using FLUENT, with the following properties:

- it should trap particules, which were released before

- it should not influence the flow in any way

Can this be realised? Maybe with a UDF?

Thanks,

Julian

I forgot to mention, that the particles, which touch the plane should be counted.

If possible, the particles should disappear after they touched the plane.

The plane itself is placed somewhere in the domain.

hello,

I know of a way but it would only be useful for post-processing. you can use a DEFINE_DPM_OUTPUT macro and take a discrete phase sample only selecting the plane you defined. in the UDF, you can use a counter variable to increment each time the sample is taken at the plane. to trap the particles, you can use the following statement:

p->stream_index=-1;
