Did you make sure that you put " ../Position " in Position Data Path on the initial data of your smoke object? For my case that was the problem.

Hello, In order to have better collisions in my simulation, I lowered my CFL condition and increased my max substeps (on the solver). Inside my pyro solver, I saw that on the gas substep, the CFL condition was divided by the timescale, I would like to know why? Do you know how exactly the CFL works? Thank you in advance, (I made a basic scene to highlight my question) PYRO__substeps_cfl.hipnc PYRO__substeps_cfl.hipnc
