Vyacheslav (hitrpr) updated subscribers of T51302: "Boid" Force field does nothing; should be removed.

@Sebastian Parborg (zeddb)
it seems this is still not solved. And not documented.
I tried to use attractor (goal) with force field and it changes nothing.

Simone (Melkor98) added a comment to T66919: Force field (wind noise) does not affect dinamically the hair particle effects.

Thanks for replying, using a small ammount of noise in the force field WITHOUT hairy dinamycs enabled help to create a lite animation for a large ammount of hair particles without need for long bakes and physics configurazion for the hair particles effect, things that (for me at least) usually takes a lot less time without quality loss in much scenes, configuring physics and baking everything takes much more time for pretty much the same result on not important things, the force field noise animation without hair dynamics enabled is a feature that i personally use a lot, and i wouldd really like to use it in 2.8, so i created this post... (For the people that says it is just a glitch animation, it is not, in the example file in this post i just made a random situation to se the animation bug, with a bit of configuration the result is really enjoyable for a lot of situations)

If you want to keep the ridgid body settings (but for some reason wont those object not to participate in the simulation), why not move the objects to a different collection [not the RidgidBodyWorld one]?

Nils Thuerey (n_t) added a comment to T59995: Mantaflow Review.

@Brecht Van Lommel (brecht) Okay, yes - the GIL seems to be unproblematic so far. It could make the UI somewhat unresponsive when baking large sims, though. The new node system notes look interesting. I think for mantaflow it would neat to go for the "everything-nodes" direction, where a node graph would define the data flow of the simulation. This could then use a python back-end, or directly hook into the mantaflow functions (the functions that are exposes to python are the crucial ones that ideally would also be available as nodes). It's definitely a good point to keep in mind.

Brecht Van Lommel (brecht) added a comment to T59995: Mantaflow Review.

Ok. The main concern is not so much that it's slow for fluid simulation by itself, but if multiple performance sensitive areas use Python it does become a problem to have these global locks. If this is how the Mantaflow API works and it's a big burden to use C++ instead it seems acceptable.

Apr 18 2019, 5:00 PM · Physics, BF Blender
Nils Thuerey (n_t) added a comment to T59995: Mantaflow Review.

@Brecht Van Lommel (brecht) Good question, to add to sebbas comments, there are a few reasons for the python bindings: a first mundane one is that that's how the mantaflow solver worked originally, and it would have been a lot more work to switch to C/C++ bindings. Also, the performance impact is negligible, as mantaflow provides all the solver building blocks via python, but each of the steps is quite expensive. So there are no low-level operations in python (e.g. access to grid cells), but just a small number of calls to high level functions that typically make several passes over the full grid.

Sebastián Barschkis (sebbas) added a comment to T59995: Mantaflow Review.

@Brecht Van Lommel (brecht) Right now the only way to access all Mantaflow functions is through Python. In terms of performance I wouldn't say that this is an issue. Once the Manta solver acquires the GIL it will compute one "step" and only once completed release it. The time between steps where other resources (like the UI) can acquire the GIL and Manta has to wait for it would be the only delay during a bake job. This delay is negligible from my experience unless there are other resources that could block the GIL for a very long time.

Hi everyone, great to see the manta integration being re-revived! @Sebastián Barschkis (sebbas) thanks for the large patch collection. I just checked out and tried the revised diff "from scratch". Works nicely on my MAC. The sims also run through without problem (I tested based on the quick-smoke and quick-liquid setups). So I think this patch looks good, overall. There are some obvious next steps, like removing the old liquid/smoke modifiers, and cleaning up the code, but I think this would be better to address once the manta code is integrated.

Sebastian Parborg (zeddb) assigned T63238: Soft body simulation that previously work in 2.79 does not work in 2.8 to Sergey Sharybin (sergey).

I'm getting this error printed in the terminal (probably related to this issue):
