How to Solve Partial Differential Equations with the MOLE

TIME: 3:30 PM LOCATION: GMCS 314 SPEAKER: Jose Castillo, San Diego State University ABSTRACT: MOLE is an open-source library that implements high-order mimetic operators. It provides discrete analogs of the most common vector calculus operators: divergence, gradient, curl, and Laplacian. These operators act on functions discretized over staggered grids (uniform, nonuniform, and curvilinear), and they […]
