XELLPACK: An Interactive Problem Solving Environment for Elliptic Partial Differential Equations
Jophn P. Bonomo, Wayne R. Dyksen · Purdue e-Pubs (Purdue University System) · 1988
ELLPACK is a very high-level language designed for solving second order, linear elliptic partial differential equations in two and three dimensions with Dirichlet, Neumann, mixed or periodic boundary conditions.The typical elliptic problem solving process is iterative; one repeatedly computes a solution, anal;rzes the results and then modifies the solution process.To better serve this process, we have developed XELLPACK, an e>..-tension of ELLPACK based on the X windowing environment.XELLPACK provides graphics inpu t for constructing grids, popup menus for selecting solution techniques, and color graphics output for analyzing solutions.Using the X paradigm, a user can interface with XELLPACK from any X workstation while an XELLPACK client solves an elliptic problem on any machine or machines on the network.
