Error codes from 1 to 99 indicate not enough space in some array. As currently implemented, these errors are unavoidable and you should try to reduce the size of the generated mesh before proceeding. Error codes >= 100 mean that the input specification is incorrect, there is a program bug, or the tolerance TOL is too small or large (try calling INITCB with a different TOLIN value).
