1. A method for increasing computational efficiency of a computing system during calculation of fluid fluxes in a reservoir model, the method comprising:
generating a set of grid blocks based on a hybrid grid mesh;
selecting a set of scaling factors that include a pore volume scaling factor and a fracture hydraulic transmissivity scaling factor;
determining whether a fracture aperture distribution is isotropic wherein:
based on a determination the fracture aperture distribution is isotropic, a scaled cross-flow equilibrium-cross-flow equilibrium (CFE-CFE) relative permeability is calculated for each grid block in the set of grid blocks, or based on a determination the fracture aperture distribution is not isotropic, a fracture relative permeability that is transversal to a cross-flow equilibrium (CFE) is calculated for each grid block in the set of grid blocks,
the set of scaling factors are used when calculating the scaled CFE-CFE relative permeability for each grid block in the set of grid blocks, and
the fracture aperture distribution is isotropic when changes in hydraulic transport properties are equal in a plurality of directions in the set of grid blocks;
calculating fluid fluxes of the set of grid blocks using the scaled CFE-CFE relative permeability; and
presenting the fluid fluxes.
