I am trying to simulate lagrangian particle tracking and want to add 1e05 particles only once in the flow. However with the patchinjection script below the number of particles keep adding after every time step. What should I do to inject particles all at once during the starting of the flow? I am using windows 17.10 version of openfoam

type patchInjection;
massTotal 0;
parcelBasisType fixed;
patchName INLET;
nParticle 1;
parcelsPerSecond 1e9;
duration 1e-4;
flowRateProfile constant 1;
SOI 0;
U0 (0 0 0);
type fixedValue;
value 5e-6;

Hi Shanvach,
Check if the time step in your controlDict is also 1e-4. If it is, then I see no reason why it should continue injecting parcels in subsequent time steps.
