A method for generating one or more visual representations of a porous media submerged in a fluid is provided. The method can be performed using a computing device operated by a computer user or artist. The method includes defining a field comprising fluid parameter values for the fluid, the fluid parameter values comprising fluid velocity values and pore pressures. The method includes generating a plurality of particles that model a plurality of objects of the porous media, the plurality of objects being independently movable with respect to one another, determining values of motion parameters based at least in part on the field when the plurality of particles are submerged in the fluid, buoyancy and drag forces being used to determine relative motion of the plurality of particles and the fluid, and generating the one or more visual representations of the plurality of objects submerged in the fluid based on the values of the motion parameters.

Method for simulating fluids interacting with submerged porous materials

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. The secondary material can include a layer portion positioned between the plurality of first particles and an outer portion. At least one boundary condition might be assigned to a boundary positioned between the layer portion and the outer portion, the at least one boundary condition includes at least one pressure value. Values of motion parameters might be determined by applying the at least one boundary condition at the boundary and generating one or more visual representations of the primary material interacting with the secondary material based on the values of the motion parameters.

Method for generating simulations of fluid interfaces for improved animation of fluid interactions

Some embodiments of the present disclosure disclose systems and methods for computing frictional contacts of topologically different bodies in a graphical system. For a large number of fibers interacting, such as hair, interacting with one or more other bodies having different properties, the problem may be decomposed into an elastic relaxation part and a contact projection part, which may be solved to yield velocities for portions of objects, providing efficient, realistic interactions.
