If I understood it correctly from the image preview and Emlplsn's replies, there are several attractor curves present. In that case, definition might look like this:

You might need to decrease the "S" input of the "SqGrid" component in order to get more rollers and therefor better final result. I can not do that, my PC is junk, even with this number of rollers it takes about 4,5 minutes to load.

Awesome!!!... can we see the GH definition please!!! :O

Thank you emlplsn.
I guess the vortex curve itself is an attractor curve?
If I can see it correctly there are few vortex/attractor curves out there. Did you used the same definition just lowered the "c" parameter by 1 or 2, and in that way got those other few curves?

Only t is a variable with more than one value (vector). The rest of them are just constants.

Thank you for the reply.
But what range of numbers did you use for a,b,c,d,t ?
Can you post the definition screenshot? At least that part related to curve creation?

Thanks djordje. I generated the vortex geometry with the mathematical function-component by using the following parametric equation:

fx(t) = a*t^2*sin(b*t+c)+d;
fy(t) = a*t^2*cos(b*t+c)+d;

Nothing fancy at all. Cheers

Very interesting !!
What are those vortex patterns? A component, or?
