This is an implementation of the smoke fluid settlement based on the BiMocq2(2 levels of Bi-directional mapping of convective quantities) method to obtain a more detailed, more precise and stable fluid simulation. This implementation is done using houdini so that Houdini users can easily apply it in their daily work. This implementation is slightly different from the original paper. The order of the algorithm steps is slightly adjusted, and the final method of affecting the speed variable is changed to better fit Houdini's original smoke simulation.
