Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to stop fluid simulation from exploding?
If all else fails, you may want to consider a premium addon like FLIP Fluids, which in my experience feels more stable than the default fluid sim, though it may be a bit costly. Consider trying the demo.
- Is there any way to get Flip Fluids for free?

Fluid Simulation Failing to Complete Render
For troubleshooting conflicts between addons, it can help to test in a fresh Blender environment with default settings and installing/enabling addons one at a time. In case it helps, we have some instructions here for how to backup user-preferences, test in a clean environment, and then restore your original addons and settings: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Baking-Crash-Troubleshooting#testing-the-flip-fluids-addon-in-a-clean-installation-of-blender

Have you ever seen a Blender donut like this?
There's a free demo if you would like to try it out: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/FLIP-Fluids-Demo-Addon

FLIP-Fluids Compiled Addon!!! Works with Blender 3.4 :)
The above was built from the code on the GitHub repository, which is under the GNU General Public License. This license allows for redistribution. Unfortunately, I do not have binaries for MacOS or Linux since I only use Windows. Also, note that the above download is for Blender 64-bit (which should be the default on the blender.org downloads page). The GitHub version doesn't have pre-made materials like the paid version on Blender Market. (Note: The demo file on GitHub has watermarks on the simulation. This is the full version of the addon, not to be confused with the demo.)

Flip Fluids ignoring obstacle
Make sure that your objects have correct manifold/closed/watertight geometry. See this topic for more info and how to verify geometry: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Manifold-Meshes

Thick & Thin Liquid Mixing Test
This is also an open source project and we provide a free version with the source code here including build/compile instructions: https://github.com/rlguy/Blender-FLIP-Fluids

Trying out some FLIP fluid simulation
Thanks! Mostly by reading through the FLIP Fluid Wiki and watching some tutorials on YouTube.

Blaze: A High Performance C++ Math library
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...

Does anyone know any good open source project to optimize?
I suspect most C++ physics libraries like Box2D (https://github.com/erincatto/box2d) or Bullet3 (https://github.com/bulletphysics/bullet3) could really benefit a lot from SIMD.
- After months of work, I'm excited to share the first release of Godot Jolt, an extension that integrates the Jolt physics engine into Godot, demonstrated using GDQuest's RoboBlast
-
X4's Upcoming Multiplayer Features Are a Huge Step Forward
No, they replaced Bullet with Jolt. That is considerably more than "some adjustment", regardless of what you think of the result.

Ive been programming for four years and I told my dad to watch long videos and complete your own projects to learn most efficiently. He thinks he’s ready to tackle any project after a ten minute video…
The first two have a bunch of great examples, and I’m tying them together by refactoring some of the THREE examples to fit the ECS paradigm defined in AFrame. then upping the ante by adding physics using AMMO, which is more challenging since it’s only a partial implementation of Bullet, and already poorly documented (yet popular) physics engine.

Their music is just too good
Plus, SM uses a system called bullet physics, I imagine this would be rather complex to rework into a modern engine such as Unreal or Unity (after all, the majority of performance issues come from the physics engine rather than the graphics engine)
-
Is anyone working on more effecient HDT-SMP?
The physics in HDT-SMP are actually being calculated outside of Skyrim's engine with Bullet, an open-source physics engine. So this isn't some limitation of Skyrim's engine.
