Claim One:
1. A computer-implemented method for modeling fracturing fluid leak-off in a subterranean formation, the method comprising: modeling, with a reservoir block flow model, fluid flow in multiple fluid phases and in multiple spatial dimensions within reservoir media in a subterranean formation; modeling, with a fracture network flow model, fluid flow within a fracture network in the subterranean formation; modeling, with an interface flow model, fluid flow between the fracture network and the reservoir media, wherein the interface flow model comprises a filtration with linear-invasion and crossflow (FLIC) model with a time-dependent pressure drop across a filter-cake on a fracture face; wherein the reservoir block flow model includes a mesh representation of the reservoir media, the mesh representation including a plurality of mesh elements, the mesh representation bounded by a boundary, the boundary representing fractures of the fracture network; wherein the mesh representation comprises coarser resolution mesh elements in the middle region and finer resolution mesh elements near the boundary; wherein the fracture network flow model includes a first system of differential equations, the reservoir block flow model includes a second system of differential equations, and the interface flow model includes a third set of equations that couples the first system of differential equations with the second system of differential equations; and generating output data representing characteristics of fracturing fluid leak-off from the fracture network into the reservoir media, the output data generated based on coupling the fracture network flow model, the reservoir block flow model, and the interface flow model, wherein generating the output data includes making time-dependent modifications to the mesh representation that includes the plurality of mesh elements.
