MULSIM/BM - A structural analysis computer program for mine design

This Information Circular presents the improved features of the MULSIM/BM program. The four major improvements are (1) ability to specify up to 26 material property sets, (2) a new material model capability for gob and inserted materials such as packwalls or cribs, (3) ability to model a large area with a grid of undivided blocks and to subdivide only a specified fine-mesh portion of these blocks into elements, and (4) specification of extraction ratios for the undivided blocks. In addition, an interactive graphics mesh generator program was written to accompany MULSIM/BM. A complete user's guide and program listings are included. The MULSIM/BM and mesh generator programs are available on tape from the National Technical Information Service.
