The inter-node average fluxes and average pressure gradients associated with the coarse grid are then used to calculate upscaled permeabilities associated with the coarse-scale grid.

Its coarse mesh is ideal for leaves and large textured debris.

The effect of negligence is enhanced by the large coarse knitting (elastic or hosiery) and large details – asymmetric collars and pockets located in the most unexpected places.

In practical terms, a “fine mesh” that is constructed from a large number of small computational cells provides a more accurate prediction than a “coarse mesh” of larger cells.

Namely, the portion having a high population density can be expressed by a fine mesh data area, and the portion having a low population density can be expressed by a rough mesh data area.

Through this approach, two discretization schemes are considered, namely a fine mesh that accounts for the micro structure and a coarse mesh that encapsulates the former.

In another embodiment, the shield may be incomplete, i.e., a grid, coarse mesh or a solid shield only enclosing a portion of the circuit; this shield is connected to the non-reference input of the circuit.

The coarse computational mesh comprises a plurality of cells.

The method includes constructing a coarse computational mesh for the reservoir.

During volume mesh generation, intersected surface triangulations are received to enable mesh generation with cell division of an initially coarse grid.

A convection-diffusion subsurface process may be evaluated on a coarsest computation mesh.

The inter-node average fluxes and average pressure gradients associated with the coarse grid are then used to calculate upscaled permeabilities associated with the coarse-scale grid.

Its coarse mesh is ideal for leaves and large textured debris.

Solver iterations performed on the coarser grid in reduced processing time generate a better initial estimate, resulting in fewer of the more expensive iterations at the fine-grid level.
