Hi aquarien, good to hear you got some first tests to work within Blender. Overall, I think several points you mentioned can be explained by the fact that the solver in Blender was developed focusing on the visual quality of the results, and not the highest physical accuracy. You mention the fluid i...

Hi, yes, that's possible - just create a new domain, and click on the file selection button at the bottom of the BAKE etc. options panel (the output directory one). Then choose one of the fluidsurface .bobj.gz files that were generated, and you should be able to view your simulation. Regards, -> Nils

Hi, the resolution setting is only for the longest side of your domain - so making the domain as small as possible, like you did, is a good idea. The multi-threading is not so easy, but might be included in an upcoming release - it's also a compiler issue... Regards, -> Nils

Hello, sorry - I forgot to mention, I'm using scons with a configuration similar to config/win32-vc.py, together with Visual Studio 2005 (Version 8.0.50727). The whole compilation works fine, but linking aborts with: LINK : error LNK2001: unresolved external symbol _mainCRTStartup The setting "/ENTR...

Hi, which gcc version comes with slackware? I usually use Ubuntu with gcc-4.1, which works fine.

Hi etr9j, sorry to go off topic here - but you seem to use MSVC8 a lot, so I thought you might have some solution for the following problem: I get the error message "unresolved symbol _MainCRTStartup" during linking. Changing the /ENTRY to "main" for linking works, but crashes when starting the .exe...

Hi, I never used OpenCFD but it sounds pretty good! It's more targeted towards engineering applications, though - so you'll probably have trouble making "cool" animations even if you have things like combustion&heat transfer... But it would definitely be interesting to e.g. compare some elbeem setup...

Hi, versions before 16th may had a bug, so if you try a newer version (e.g. the one from the 29th) it should work...

But please test :), now e.g. deforming meshes such as animated characters should work.

Thanks, -> Nils

monkeyman23555: The baking times depend on the resolution setting, which determines the "number of equations" you have to solve, so there's simply a lot of stuff to compute... :) ZanQdo: Thanks for the files, I tried both with my Linux build, and a recent win32 build (http://blendertestbuilds.de/ind...

Hi LetterRip&All, the existing code is voxel based but creates a triangle mesh for displaying the water surface. on itself, a smoke simulator is simpler than a free surface one, but I think the main problem in Blender currently is that there's no way to display volume data such as smoke... It would ...

lucky3,kmaro: so you get fluid meshes that look like that, when you set the domain boundary to "noslip"? That looks really strange... kmaro: did you compare 2.41 and test build bake times? how much is it slower? It shouldnt be any slower from what I changed... lguillaume: no plans for next summer of...

womball: sorry, that was just me dreaming :) - for realisitic pictures, it would certainly be important, but it's not really easy to integrate a proper photon map support into the Blender raytracer... For the rest, it should be possible to render pretty cool fluids now with the hdr support, motion b...

Hi, I guess you saw there's another thread with an up to date version - please test :) , I'm sure there are still a lot of issues...
