OK, so I have this problem : I just learnt 2 days ago the principles of fluidism in Blender and I tried the tutorials : Basic and second stage fluidism. They are (my guess) rather simple. The first one was only with a Cube-domain and an IcoSphere-fluid. The second was like this, but it had and obstacle-a glass (more of a cup!) And it worked.
Now to my problem. I tried reproducing it by making a personal map, that had a Cube-domain, an IcoSphere-fluid and some kind of plate-obstacle. Now, hear this. The fluid, went THROUGH (yea, through, as in some kind of net) the plate. I’ll try to put some photos… That happened every time I tried the simulation. I tried the 55 resolution till 25 resolution (the one that increases the size of the simulation temp files)… still nothing. Here are some photos.
Thanks!
PS:I tried the simulation in Blender 2.43 RC3 and Blender 2.42a Flash Version… the tutorial was built on 2.37 but I looked at the changes page.
For more accurate collision you want to increase the resolution, not decrease from 55 to 25. Set it to about 100, delete the old bake files, and re-bake. Post back if it still doesn’t work.
(Or if it does…)
PS If all else fails, try subdividing your bowl mesh once. (Although it looks like it should be dense enough to work.)
Are you serious? Doing the 100 res works?? If yes, that is so bad because now I have only 512 MB ram on 66 MHz (although the specs at the store said 533, but all tests confirmed 66) That is not what I had in mind, but really thanks!
No, dude. Doesn’t work… 
I tried 4x subdivision on the bowl and 125 res. Nothing!
Nah, it doesn’t work at all… Worse, it takes much more time for almost the same effect… Am I having some kind of ruined Blender collection or what?!
Check the normals on your bowl are all facing outward. Edit mode, select all vertices and press ctrl+n to recalculate normals outside. Then, make sure that your bowl is set as an obstacle using the volume of the bowl (select init volume).
I hope this helps. I am having some problems with fluid sim at the moment, myself. Trying to knock a drink can over while it’s half full.
Well, thanks, I thought that would be the case, but I checked it already… And no, it’s all there. All the normals are so outside they might get cold (yea, not funny, I know!!) And, the stupid part is I managed doing that animation you’re talking about. But then again, I tried again the 2nd tutorial on BlenderWiki on Fluid Simulation… the damn thing works now, I did it. But, as always, when I try to do another thing, that is like the tutorial, I just happen to SCREW it (sorry 'bout the language, but yea, it really screws, like turning into a tornado!!). But I found a thing in the tutorial that specifies something about the DOMAIN having to be on SMOOTH. Here’s the quote… *ahem!
"Step 10) Switch of the shaded mode with the ZKEY, and add a cube around the center of the glass. Scale it up to be four units on each side. In side view align the bottom of the cube with the floor plane, and name it “Domain”. Finally enable fluid simulation and make the cube a domain, and set it to Smooth shading in the Editing buttons right away. (Note that the domain box is cubic in this case, but in general it doesn’t have to be.) "
So, I will set now on smooth the domain. Plus the guy is desperate to name the Fluid Sim parts… like Glass, Domain, Floor, etc…
So, I would very much like to know this was the only friggin problem. Thanks, and see ya’!
Well, worst case scenario I think you’re looking at a bug in rc3. It should work at this point. Are you getting any interaction at all, or is the fluid just acting as if the bowl isn’t even there? Make sure everything you want to interact is inside the domain when you bake. That’s really all I can think of right now.
No, actually, I checked the interaction thing down… it’s on 1. I tested it on 0 and it was like absorbing the whole fluid! And, no, I tried it on 2.42a, which was the only release at the Download section. I found these early releases of 2.43 on the Blender News.
Yet, I think I have the problem almost solved. The thing that must retain the liquid must be thick enough. I mean, I tried extruding the whole obstacle, which is a cup. I tried simulations with it scaled at 1, 1.1 and 1.7. Then I noticed it started to leak lesser as the mesh was thicker. So, now I got a thick cup, not too thick, mind you… It would be inestethique ( or whatever ) . But I hope they resolve it by the time its official release is… um… released. And thanks for all your sugestions, LoTR Junkie and dodgydavec!!! Nice.
did you try on the obsticle choosing init both?
if you do that and bake at a higher resolution, it is less likely that anything will mess up
if you’re really looking for an accurate sim, bump the res. to something like 170 or 200.
ignore the estimated memory it will take because i have found from several fluid sims that those numbers are just not true
be sure you bake each time you change something, so that blender recalculates the fluid glob mesh shape. I was making that mistake and it was very confusing to me, as I would change the cup and the fluid kept doing the same thing, because I was not re-baking.
Nah, it was nothing really. And, the one with try extra resolution… Well, I cannot afford this right now. I have to wait till easter. I haven’t got that ammount of RAM, I only have 512 MB :p. I will try that later… Oh, and I tried the both init.
And the second dude, no, I was sure to delete all the temp GZ files… these gave me enough trouble in the first place. But now I try on thick things. I have to extrude and resize the whole mesh.
