I would like to do some serious fluid simulations but fluid sim in newer Blender versions(2.57b + various graphicall builds) seems to be more buggy than in previous. Before I start working on real sims, I would like to do some stability/speed tests.
I bought a quite powerful pc some time ago, spec:
- INTEL Core i7-2600k 3,4GHz 8MB LGA1155 (PCU)
- ASUS P8P67 PRO rev3.0 (Motherboard)
- GIGABYTE GTX570 1280MB DDR5 2xDVi/1x miniHDMI (Graphics Card)
- 8GB DDR3 KINGSTON HyperX Genesis 1600MHz (RAM Memory)
- OCZ 700W StealthXStream 2 (Power Supply)
- SAMSUNG 500GB HD502HJ 16MB cache SATAII (Hard Drive)
System: Windows 7 Home 64bit
Some time ago I did a lot of fluid sim tests on my crappy almost 5 years old laptop (dual core 1.6 GHz, 2.5GB RAM 667 MHz, integrated graphic card). Even on this old and unsuitable for fluid sims machine I could bake fluids with resolution over 200/250 maybe more. Sometimes it crashed but it was quite stable.
Now on my much better pc I have a lot of crashes. I spotted several situations:
- simulation resolution set over 200, sometimes even over 100
- Blender can crash, freeze operating system (no reaction) or bake only part of frames correctly
I’d like to do bug(s) report and think about fundraise to polish fluid simulation if devs would be interested (preferably Daniel Genrich and/or Miika). I also tested graphicall builds with OpenMP (for multithreading) but with poor results. It is much more painful as I’ve got a 4 core CPU now (and I know a lot of people have much more powerful PCs).
I attach my test sceene made in official Blender 2.57b 64bit. I used “make fluid” operator and tweeked settings. I also applied scale to domain object, but tried without this also. If You could test and confirm bugs/system freeze it would be cool. Remember to set correct path to bake directory.
Write what You think about fundraising for simulation polishing (I know about gsoc but It would have quite different goals).
Best regards, Dawid. Sorry for my poor English.
