Hi BlenderRicky, I’ve modified your blend so it should now create a fluid animation. I’ve changed your domain to a cube, moved the fluid so it does’t intersect the obstacle and changed the obstacle to a shell.
but i was not like that in the video
don’t know if you had chance to loo kat it !
but when you bake the domain dissapear
so how to procede to re- bake again?
when you do the baking this means that all the material color Mirro Tranps have been set
cause this cannot be change afteward!
the sphere was not big so may be it did not have enough volume to fill the bottom of the glass?
also for the domain you set final rendering i think
what does it change ?
i want to try on to make a river with Shay Tessler
see post http://blenderartists.org/forum/showthread.php?p=1384860#post1384860
with different wya to do it and fluid might be the best way to do it!
but not certain about it
blender does not have any reflection on the liquid i think this may have to rendered with yafaray to get the best results!
i think this require the fluid volume top be inward or outtward i think
would it be possible to help with this one too
you can find the file at the same place
file is called river
it 's a very sinple model a small mesh for the land and a river in the middle
i tried to find in wiki some good PDF tut but could not
dont understand why there is so little on this subject ?
It can be confusing but the domain is the object which actually turns into the fluid during the baking. The ‘fluid’ object is just used as a starting point. You can still see it along with the fluid domain. Move the fluid to a new layer so it does not show up during renders. To change properties and rebake, just select the domain (which after the first bake looks like the fluid.
The material you want for the fluid in the render needs to be applied to the domain object. You can have more than one obstacle in your domain.
For ripples on the fluid you need a high resolution.
This Video I made with the attached blend. The resolution was set to 240 which takes an age to bake and render and needs lots of ram. The video is about 14 secs long but simulates only 0.4 secs of a fluid. If it was a real time simulation you would never see the wave details.
Change the shape of the domain so the fluid object is completely in it. You can make it higher without a problem, the only important thing is its longest side. I would also Cntl-A to clear scale and rotation.
Make the fluid an inflow so there is sufficient fluid to flow down the slope. Give it a little -Z and -Y initial velocity
By default, obstacles are sticky. Change the boundary type to Part or Free
Increase the fluid resolution as high as is practical. Maybe also add some surface smoothing.
Set the realworld size of the domain to a realistic figure. Maximum 10m but if too high the slower to bake.
Adjust fluid flow by adjusting size of the fluid object and the inflow velocity settings. It needs to be high enough to give you initial flow but if too high it will splash out the river. I changed the obstacle boundary type to Free so the fluid doesn’t stick to it. I want the fluid to flow as smoothly as possible down the river and around the obstacles.
