Abstract
The proposed numerical procedure for static open boundary problems combines fast adaptive multigrid methods with spatial mappings of the infinite region to a finite computational domain. A rigorous analysis of the finite element solution error for ballooning and for spatial mappings is presented. The method is applied to geophysical problems of delogging
