Abstract
The notion of invariants associated with differential equations introd uced in Part I is used to compute consistent local errors in a finite- element analysis. The procedure is illustrated by two simple examples- a one-dimensional beam problem and a two-dimensional membrane problem. It is also shown how the computed errors may be used for adaptive mes h refinement. However, the primary intent of this paper is to introduc e a new concept for calculation of local errors.
