The Very Large Eddy Scale (VLES) turbulence modeling approach ensures that anisotropic fluid structures are captured with high fidelity, which is critical for aerodynamics and aeroacoustics workflows The fluid space is automatically discretized into cubic voxels, and boundaries into surfels, eliminating the need for conventional surface and volume grid generation. Lattice Boltzmann methodīased on a discrete form of the kinetic theory of gases, the Lattice Boltzmann method tracks the microscopic motion of fluid particles through discrete space and time, to simulate the flow of gases and liquids. Additional discretized transport equations can be solved in the same way to represent other physical phenomena like turbulence and chemical species. The resulting set of algebraic equations is solved iteratively to obtain the pressure, velocity, temperature (and other physical quantities) in each cell for steady or unsteady flows. The finite volume method is used to discretize the continuum equations that describe fluid motion, known as the Navier-Stokes equations. The physical space to be simulated is divided into many small sub-domains called control volumes or cells.
