Abstract
The proposed numerical procedure for static open boundary problems combines fast adaptive multigrid methods with spatial mappings of the infinite regi on to a finite computational domain. A rigorous analysis of the finite elem ent solution error for ballooning and for spatial mappings is presented. Th e method is applied to geophysical problems of de logging.
