SPRINT2D is a set of software tools for solving both steady and unsteady partial differential equations (PDEs) in two-space variables. The software consists of a set of coupled modules for mesh generation, spatial discretization, time integration, nonlinear equations, linear algebra, spatial adaptivity, and visualization. The software uses unstructured triangular meshes and adaptive local error control in both space and time. The class of problems solved includes systems of parabolic, elliptic, and hyperbolic equations; for the latter by use of Riemann-solver-based methods. This article describes the software and shows how the adaptive techniques may be used to increase the reliability of the solution procedure for a Burgers’ equations problem, an electrostatics problem from elastohydrodynamic lubrication, and a challenging gas jet problem.

This software is also peer reviewed by journal TOMS.
