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.

A graphical user interface (GUI) is configured for displaying surfaces of simulated objects within a scene. The GUI comprises a selector to choose between displaying the scene as: a plurality of particles, wherein each particle comprises a plurality of attributes; a plurality of ellipsoids formed from the plurality of particles, wherein dimensions and orientation of each ellipsoid depend on the number and direction of neighboring ellipsoids within a search radius of the ellipsoid; or one or more splatted or rasterized surfaces formed from the plurality of ellipsoids. The GUI further includes a display window within which the GUI displays the scene.

Graphical user interface for creating data structures used for computing simulated surfaces for animation generation and other purpose

A method for generating visual representations of interactions between two different materials is provided. The method can be performed using a computing device operated by a computer user or artist. The method includes modeling a primary material as a plurality of first particles and modeling a layer portion of a secondary material as a fluid volume.

A simulator computes surfaces corresponding to objects in a simulation by computing covariance matrices for particles that use a square root of a diagonal matrix. The simulator might operate by receiving positions and sizes for each particle of a plurality of particles comprising a first object, identifying a subset of the plurality of particles whose positions are proximate to a first surface of the first object, deforming particles of the subset of the plurality of particles by generating a covariance matrix for each particle of the plurality of particles, using a square root of a diagonal matrix, wherein the diagonal matrix is a diagonal matrix of neighboring particles for each particle of the plurality of particles, and computing the first surface of the first object based on the deformed particles.

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.
