openCL error on simple vellum fluid sim Aug. 1, 2026, 6:51 p.m.

Hi everyone! So I just was doing a quick test and dropped a sphere and just hooked up a vellum configure fluid SOP right after it. Didn't change any parameters. Then, I dropped down a vellum solver and hit play and it didn't even get to frame 2:

The error I received was:

This is only happening on Houdini 22. I opened Houdini 21 build 512 using the exact same setup and the sim ran just fine in Houdini 21. Is there something that I'm doing wrong in Houdini 22. Can anyone give me some guidance?

Also, my NVIDIA driver is 610.88

Padding issue with pyro configure fireball Dec. 28, 2025, 6:07 p.m.

So I was just playing around not doing much of anything. Just having fun and I threw down a pyro configure fireball and started running it when I ran into something curious. I attached an image of one of the sims that came out from it. It looks like the flames are hitting a wall which I naturally assumed was a padding issue with the simulation. So I increased the padding, but that didn't fix it either. I was running the simulation in sparse mode. I changed it to dense and ran it with OpenCL and that sort of fixed it, but there was still a bit of clipping. The image attached is looking down at the fireball orthographically. Anyone have any ideas why this is happening? Maybe I'm missing something.

I see! Thanks for the reply. Those examples really help!
