ZanQdo: multi-threading the simulation itself isnt easy, but definitely planned... but right now it's not yet working. modifiying the inflow velocity should be possible soon by ipos for each velocity component. but you're right, an object local velocity would be easier to handle... cekuhnen: it's ba...

simhar: the method was developed to do optimizations of metal foaming processes, so there's a physical background and it should approximate the underlying equations quite well. For any simulations with physical relevance I would recommend doing some accuray tests first, though... This powerFLOW soft...

hi Nick_Lambert, bad to hear - could you try to get the command line output (by starting Blender from a console or so)...? That sounds like the wrong python version, or some library problem.

nozzy: looks like an instability, the moving objects are more critical with respect to stability... lucky3: yes, fluid in a moving glass is something like a worst case. Higher resolution or slower movement might work better, but i'll probably just have to implement some more stuff to get that right....

Yes, the fluidsim frame numbering is currently a bit stupid, I'll have to fix that... But the xml-option with yafray shouldnt really be affected by that. Gerd: maybe you can test if it works if you render without the fluidsim, or post an example .blend file.

Koba: I also saw the Lightwave export thread on cgtalk - it's pretty cool :). I also learned that it's not legal to create a GPL'd plugin for a non-GPL'd program, so thats probably going to be the only way for a while... Dani: Point 1) I actually thought along the same lines - you could store per ve...

koba: you're right - for large splashes it will be impossible to resolve every small drop in the grid. I'm currently working on something a bit similar to what you proposed, basically using particles to model small unresolved drops and bubbles. The problem is that you still have to store a grid to p...

Linx Moving Objects Fluidsim Preview

Hello, here's the El'Beem christmas preview version :) (Currently only for Linux, I hope I'll have time to make some other builds next year or so.) http://www10.informatik.uni-erlangen.de/~sinithue/temp/blender-elbeemxmas-linux-glibc2.3.5-i386.tar.gz It has moving objects now as a new feature (simpl...

you could try to directly use the saved surface meshes - here's a python example how to load them into Blender:

Re: Fluid Simulator in 2.40 Alpha1

Hi! The 2.40 seems marvelous, though, I noticed a weird behaviour in the fluid simulator: - When several objects are used as obstacle, some of them are detected as obstacle and some others are not. In a test file using 3 planes as obstacles, the 1st and the 3rd are detected as obstacles, and the fl...

scons defines

This seems to be a problem with the way i added the defines in the SConscript file in combination with the scons or linux version... for a quick fix you can replace the lines: elbeem_env.Append(CXXFLAGS= ' -DNOGUI -DELBEEM_BLENDER=1 '); elbeem_env.Append(CCFLAGS= ' -DNOGUI -DELBEEM_BLENDER=1 '); wit...
