A computer-implemented method simulates an atmospheric phenomenon within a simulation volume. At each time step of a plurality of time steps, the method automatically determines a temperature distribution of the atmospheric phenomenon based on an assumption of fixed volume, and then automatically determines a velocity field of the atmospheric phenomenon, based on an assumption of adiabatic expansion.

A system and method for facilitating moving particles in a virtual space use depth information that reflects distances of objects in a virtual space to either a ground level or a viewpoint. The depth information may be stored in a set of information. The system detects collisions of particles and other objects based on the depth information, on a frame-by-frame basis.

A combustion simulation system is provided. The combustion simulation system can be performed using a computing device operated by a computer user or artist. The computer-implemented method of simulating a combustion process includes receiving a set of data representing a fluid flow. The fluid flow can include combustion precursors. The method includes simulating a chemical reaction representing simulated combustion of these precursors generating combustion byproducts. The method can include determining a change in temperature of the combustion byproducts due to the chemical reaction, determining a change in molar mass of the combustion byproducts due to the chemical reaction, determining a divergence of the combustion byproducts based on a combination of the change in the temperature and the change in molar mass, and generating data structures of the simulated combustion based on values of the fluid flow.

A method for generating one or more visual representations of an object colliding with an interface between a simulated fluid and a material. The method includes obtaining shape and movement data of a bulk fluid and an object, identifying an interface where the bulk fluid covers a portion of the object, generating an emitted fluid at the interface, generating shape and movement data of the emitted fluid interacting with the object.
