Abstract : A general purpose solver for large, sparse, banded systems of equations has been developed and tested on the CM5E. This tool can be applied to any problem arising in finite element analysis such as structures, machinery, acoustic-structure interaction among many others. For a very large problem a factorization and solution takes 10 to 12 minutes; solutions for additional right hand sides will take on the order of one minute each.
