Abstract: Geologic modeling methods and systems may use design-space to design-space mapping to facilitate simulation grid generation for multiple interpretations of a subsurface region. As one example, one or more embodiments of a geologic modeling method may comprise: obtaining first and second geologic models having different structural interpretations of a subsurface region; mapping each of the geologic models to associated design space models representing an unfaulted subsurface region; determining a design-to-design space mapping from the first design space model to the second design space model; using said mapping to copy parameter values from the first design space model to the second of the design space model; gridding each of the design space models to obtain design space meshes; partitioning cells in the first and second design space meshes along faults; reverse mapping the partitioned design space meshes to the physical space to obtain first and second physical space simulation meshes.
