Hi Foamers,

Did you know how to use particle collector function in OF?
I would like to measure how many particles are concentrate in a specific patch.

Thanks in advance and best regards,

Hi Vaganto,

Did you get a response to this question?

Hey Vaganto,

As described, particleCollector gathers summed up lagrangian data (mass and mass flow rate) through a region defined by the user.

particleCollector1
{
    type            particleCollector;

    mode            concentricCircle; 
    origin          (0.05 0.025 0.005);
    radius          (0.01 0.025 0.05);
    nSector         10;
    refDir          (1 0 0);
    normal          (0 0 1);
}

The output is stored in any the VTK folders that you generate, within each time step. There may be a PyFOAM script to plot these, I'm not entirely sure

 particleCollector1
 {
     massTotal       30 { 0 };
     massFlowRate    30 { 0 };
 }

Best,
Mustafa
