tyhero is on a distinguished road
When using momentumLookupTableInjection, there may be situations where some positions do not inject particles or only one position injects particles.
https://ss1.xrea.com/penguinitis.g1....injection.html I followed the prompts on this website to set the time step and parcelsPerSecond, but there were still issues.
Here are my settings:
Code:
model1
        {
            type            momentumLookupTableInjection;

            inputFile       "injectionTable";

            parcelBasisType fixed;
            nParticle        1;
            parcelsPerSecond 200;
            randomise off;

            massTotal       0;
            SOI             116;
            duration        1;	

        }
Code:
FoamFile
{
    version     10;
    format      ascii;
    class       dictionary;
    location    "constant";
    object      injectionTable;
}

// (x y z) (u v w) d rho mDot
(
    (0 0 0) (0 0 0) 1e-3 9341.88 1e-7
    (0.5 0.01 0) (0 0 0) 1e-3 9341.88 1e-7
    (-0.5 0.01 0) (0 0 0) 1e-3 9341.88 1e-7
    (-0.1 -0.01 0) (0 0 0) 1e-3 9341.88 1e-7
    (-0.4 -0.02 0) (0 0 0) 1e-3 9341.88 1e-7
    (-0.6 -0.02 0) (0 0 0) 1e-3 9341.88 1e-7
    (-0.8 -0.05 0) (0 0 0) 1e-3 9341.88 1e-7
    (0.7 0.04 0) (0 0 0) 1e-3 9341.88 1e-7
);
I hope someone can give me an answer.
Thank you!
