Hello everyone
I created a sph fluid simulation with Python and pyopencl. Find it
here: https://github.com/benma/pysph [1].
I would appreciate any feedback. Also, since I have an nvidia card, I
would be glad if someone using an ATI card could test it and tell me
whether it works.
Best, Marko
Finally got a chance to try this on my AMD Llano APU, no luck:
7290 particles
initial density: 1000, mass: 17.146776406, gas constant k: 1000,
timestep: 0.00407722018784
(20, 20, 20) 8000 cells

Any ideas?
