I also took care of a bug and added inital velocity support for smoke.<br /> <br /> === What&#039;s been done ===<br /> <br /> * So far I hadn&#039;t really touched the &quot;Initial velocity&quot; settings from the flow source menu. So I started off with smoke and implemented a first version. Results look promising and similar to the one from the master branch. Initial velocity for liquids is slightly more complicated. (For liquids you&#039;d have to set the initial velocity to a whole volume of particles, however, the smoke UI is more suited for planes with just one normal). I will come back to this later. ({{GitCommit|rB166c3db1e794}})<br /> <br /> * There was (and still is to some extent) a problem with domains that have outflow cells. Liquid particles weren&#039;t deleted correctly and in some situations liquid simulations appeared to have too much velocity. With the help of Nils and many example scenes (thanks guys!) [1] I managed to get the outflow problem under control. What&#039;s left are velocities. I experimented a bit and it seems there is too much velocity extrapolation before and after the pressure solve. ({{GitCommit|rB766572cd0a7a}}, {{GitCommit|rBfeda06e184ff}}, , {{GitCommit|rB3ee4f50995e0}}, {{GitCommit|rB837972517176}})<br /> <br /> * I added float particle support to the seconday particle sampling routine. Tracers remain a todo, however, there is now also &quot;Bubble&quot; particles! For now, here is a simulation of those floats and bubbles in Mantaflow. (In Blender these new files are unstable, I am still hunting the bug).<br /> <br /> [[File:Mantaflow_sndpart_demo2.gif|center|thumb|518px|Float and bubble particles inside Mantaflow]]<br /> <br /> * On the Blender side, everything is now set for float, tracer, bubble particles. That includes UI, automatic particle system setup and caching. I just have to tranfer the Mantaflow code and uncomment some lines. ({{GitCommit|rB6ed2fe0229c1}})<br /> <br /> === Next up ===<br /> <br /> * Get my Mantaflow code working in Blender again.<br /> <br /> * Add support for tracer particles.<br /> <br /> * Take more care of the Github bug [1]. Again, outflow should be fixed, velocities are still off. Fixing this bug has high priority. <br /> <br /> === Questions ===<br /> <br /> * No<br /> <br /> === References ===<br /> <br /> # https://github.com/sebbas/BlenderMantaflow/issues/7</div>
