Blender-FLIP-Fluids VS webots

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.

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

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

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.)

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

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

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

The related documentation for how to enable and use attributes (such as the color attribute) is here: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Domain-Attributes-and-Data-Settings

Open Robotics Resources - Provides guides and documentation for robotics simulation.

Deepbots is an open-source framework facilitating reinforcement learning in Webots. Webots provides easy-to-use tools to create your own worlds/robots, and deepbots interfaces Webots with any gym-compatible RL agent. It does this by guiding even the most novice users to create gym-style environments that are compatible with Webots (we have recreated the classic control problem CartPole successfully in Webots, among others). Deepbots handles all low-level details to interface the environment with the simulator.

FreeCAD has a robotics workbench, and it is free software. There's also the Webots Open Source Robot Simulator which comes with lots of robots out of the box and is also free software, meaning you can not only download and use it free of charge, you can also influence development by fixing bugs yourself or filing issue reports.
