Hi, I'm trying to use the surface elevation utility and probes to calculate velocities but I'm getting this error after a few time steps:

    add       (0 0 0.45); //( 0 0.45 0);
    axis      z;
    stretch 1.5;
}

I am guessing it has something to do with the nFreq value or else the sampling time but I'm not sure. I tried uncommenting tMax and starting tMin at 0 but this did not resolve the problem and caused the same error.

Does anyone know what this error means or where it's coming from?
