Hi,

I am looking at flow around a solid cube at different angles.


I'm interested in the pressures on a line up the centre of each façade so I manually use sample. For the 0 degree case, where flow is perpendicular to the cube:

zfront
    {
        type        uniform;
        axis        distance;

        start       (0 -3.02 0);
        end         (0 -3.02 6);
        nPoints     100;
    }

Two things:

1. Sample often doesn't produce 100 points for some reason, nor does it order them
2. As my cube turns (for different simulations), my sampling points will turn. I'd like to sample over a line defined by a trigonometric curve. Is it possible?

e.g.

start(3*sin(pi/180*Angle) -3*cos(pi/180*Angle) 0)
end(3*sin(pi/180*Angle) -3*cos(pi/180*Angle) 6)

My alternative is to make the list of points but the sample file will be enormous as I have at least 10 lines to sample over. Any thoughts would be much appreciated
