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 generating one or more visual representations of a combustion even is provided. The method includes simulating the combustion event, which transforms combustion reactants into combustion products, the combustion event occurring at a reference pressure, automatically determining values of combustion properties, the values of the combustion properties being calculated as a function of a nonzero pressure field, and generating the one or more visual representations of the combustion event based on the values of combustion properties.

Method for simulating combustion in digital imagery with equilibrium and non-equilibrium conditions

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.

Method for simulating combustion in digital imagery with variable pressure conditions

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.

Method for simulating combustion in digital imagery

A combustion simulation system is provided. The system receives data representing a fluid flow. The data includes a plurality of combustion precursors, including at least one arbitrary combustion precursor that may not correspond to a physically realizable material. The system simulates a chemical combustion reaction involving the plurality of combustion precursors and generating combustion byproducts. The system determines a change in temperature and a molar mass of the combustion byproducts due to the chemical reaction, and determines a divergence of the combustion byproducts based on a combination of the change in the temperature and the change in molar mass. The system then generates one or more data structures of the simulated combustion based on at least a portion of the fluid flow.
