Adaptive multiscale-streamline simulation and inversion for high-resolution geomodels

Properties of MsMFEM: 3 Incorporates small-scale effects into the coarse-scale solution 3Mass conservative on coarse grid and subgrid 3Scalable since basis function are processed independently 3Flexible: given a fine-grid solver, coarse cell = a collection of connected fine-grid cells 3Robust: method can always be defined and will always produce a result (in contrast to upscaling) 3Accuracy: good, provided that coarse grids follow simple guidelines 3The method is fast when basis functions are update infrequently Inversion Method
