This update introduces two improvements from the Mantaflow repository: (1) Improved particle sampling: - Liquid and secondary particles are sampled more predictably. With all parameters being equal, baked particles will be computed at the exact same position during every bake. - Before, this was not guaranteed. (2) Sparse grid caching: - While saving grid data to disk, grids will from now on be saved in a sparse structure whenever possible (e.g. density, flame but not levelsets). - With the sparse optimization grid cells with a value under the 'Empty Space' value (already present in domain settings) will not be cached. - The main benefits of this optimization are: Smaller cache sizes and faster playback of simulation data in the viewport. - This optimization works 'out-of-the-box'. There is no option in the UI to enable it. - For now, only smoke simulation grids will take advantage of this optimization.
Mantaflow
Mantaflow is an open-source framework targeted at fluid simulation research in Computer Graphics. Its parallelized C++ solver core, python scene definition interface and plugin system allow for quickly prototyping and testing new algorithms.
In addition, it provides a toolbox of examples for deep learning experiments with fluids. E.g., it contains examples how to build convolutional neural network setups in conjunction with the tensorflow framework.
