This paper presents mulsim/pc, a structural analysis numerical modeling computer program based on the boundary element approach. The difference between this program and its functionally identical predecessor, mulsim/bm, is that mulsim/pc no longer requires a mainframe computer. The U.S. Bureau of Mines has specifically rewritten the program for use on IBM-compatible personal computers. This program is designed for structural analysis of underground coal mine plans consisting of single or multiple parallel seams in any orientation. It is useful for modeling large areas and estimating the continually changing load and displacement distributions that occur throughout the mining cycle. Mulsim/pc is a user friendly numerical modeling computer program that is well suited as a general structural analysis tool for the underground coal mining industry as well as a teaching aid for academia. This paper discusses the capabilities and features of mulsim/pc and the companion pre-and post-processing graphics programs, and presents an example application analysis involving two-seam interaction.
