In the particle tracing module (using 3D mathematical particle tracing) is it possible to release the particles from a set of defined (x,y,z) points or from points along a parametric curve?
I can draw the curve in the geometry but am unable to use it to generate particles. In the "Release" and "Inlet" nodes you can only select domains or boundaries and not curves or points.
So then I tried the "Release from Grid" node and I could define ranges for x, y and z but then I get every x, y and z combination rather than (x1, y1, z1), (x2, y2, z2) etc which is what I need. So then I thought to make a range just for the x coordinate and then to define the y and z coordinates (and starting velocities vx, vy and vz ) based on the x coordinate for each particle (qx?) but I cannot find how to refer to its x coordinate - maybe there is some hidden variable I could refer to - I tried to guess it's name but without success.
Any ideas?
