Fluid Simulation in Blender
As of version 2.40, Blender has an integrated Fluid simulator. It is the result of one of the Google Summer of Code projects. It allows you to define fluid bodies, obstacles and in- and outflow of fluids. The results are amazing but you should be prepared for some long and memory-hungry calculations, especially when you’re using high-resolution meshes.
You can find the full documentation on the Blender Wiki, along with a few good tutorials to get you started:
Please note that there have been some changes in the GUI since these tutorials were written, so read these notes before you start.
Those tutorials are very helpful…thanks for pointing them out.
btw – Your blog is coming along really well. Congratulations!
Yes, really good tutorials! I still got one question that came up when building the scene with
the glass as obstruction: Is there any possibility to somehow aim the liquid at the glass,
because when I tried that tutorial some of the liquid almost always landed on the floor
instead of all inside the glass; I tried to reposition the liquid sphere but it didn’t really
help much. Any tips would be welcome!

The tutorial suggests limiting the number of frames and lowering the resolution to speed up testing. After that, it’s just hard work :)
“Step 13) Now we’re ready to start simulating: first reduce the number of frames to e.g. 50. Then select the domain object again, and just hit bake for a low-res test simulation to check if the drop really hits the glass the way we want. Playback the animation (ALT-AKEY) and view it from different angles. It’s probably a bit to slow – I ended up with a initial velocity for the drop of (0.2, 0.15, 0). Change and re-simulate until you think it’s good. You might also want to reduce the simulation end time to 0.2. “
i was looking at the tutorial and for some reason the pics won’t show. is there a problem with the website or is it my computer?
Thank you.
That tuturial has finaly let me spill fluid in to a cup.
I couldn’t do that before and I still don’t know why, but I can now.
Before, the fluid just flowed at the top of the opening as if it solid and not hollow.
You have all so lead me on to Blenders online Manual.
I now know why the yaf-ray always crashed Blender apon rendering.
I am now reading it and will learn everything about useing blender.
Thank you again, I’m in your debt.
P.S. Itreank, It is your browser.
Ether it is text base or it is set to not download the pictuers.
One other possability is that your browser dosint reconize the image format.
If so then you could try one of these web browsers free.
