Researchers from the École Polytechnique de Montréal showed that Jacket is very efficient to rapidly calculate 2D or 3D isotropic gradients in MATLAB® code. From a mathematical point of view, the isotropic gradients are characterized by their very precise orientation compared to the standard 1D finite difference discretizations. Using convolution functions developed by AccelerEyes, the method becomes very simple to apply and provides a very fast evaluation of isotropic gradients of functions or images. This type of isotropic discretization currently has an application in computational fluid dynamics. They are useful for simulating immiscible multiphase flows using the Lattice Boltzmann Method (LBM), where the orientation of the various fluid interfaces has to be computed very frequently and precisely. In multiphase flow …
