Hello everyone, my problem consists basically of turbulent liquid flow with the injection of lagrangian solid particles.

I calculate the deposition rate as the incident mass flux of particle * mag(area) or the equivalent which is the mass flowrate of lagrangian phase.

The point is that I want to count only the particles which passed through my boundary with a velocity lower than a value “x” m/s.

I tried to define a few field functions to capture the incident mass flux if particle velocity < value otherwise it is zero and tried the same for a mass flowrate of Lagrangian particle and I had no success. All scenarios I got unable to compute in my reports.

For the field function that I tried to filter using the particle velocities I used

(mag($${TrackParticleVelocity})>1.2)?0:${IncidentM assFluxLagrangian}

I expected to have only the incident mass flux of Lagrangian for particles with velocity lower than 1.2 m/s
