A method of extracting configurations from assemblies of CAD parts with both large and small features. The technique uses a nested set of Cartesian cells as well as adjoint-based adaptation. Small features are initially ignored and are only resolved if needed; thereby saving computer time and memory. Configurations that are composed of assemblies of parts are handled automatically by the method and a user thus does not need to artificially close a configuration first in order to generate a computational grid. Adjoint-based adaptation is used to automatically select those features that need to be resolved. This step, when combined with field adaptation, yields a highly-effective method of computing flows over a variety of configurations.
