Questions about cylinder sampler

Hello,

I write because I observed some weird behavior with the random sampler in cylinders.

I attached a very simple test which samples particles with a given radius (1), in a disk of a given radius as well (20).

When running it and print the distance to [0,0], I obtain values that are well above 20.

Looking at the source code of the sampler, I do not really understand why. Do you have a clue of what I might be doing wrong?

Best regards,

Yves

Yves,

You have a bug on this line:

auto points = sampler.SampleCylinderZ((0.,0.,z_cylinder), r_cylinder, 0.0);

It should be:

auto points = sampler.SampleCylinderZ(ChVector<float>(0.,0.,z_cylinder), r_cylinder, 0.0);
