How does fluid simulation work on a high level? What are the 3 main operations?
Think of a fluid as a collection of boxes or cells. Each box has various properties, like velocity and density. These boxes interact with their neighbors, affecting their velocity and density.
For one simulation there are 3 main operations.
Smaller time steps ...
always improve stability
At static equilibrium...
the system is in a state of minimum potential energy and the total forces are gone for all nodes
Large time steps typically ...
speed up the simulation
Inertial tensor is invariant to object orientation?
True
What methods of collision responses are there?
