... that conform to the complex geometric features present in the subsurface. However, running a million-cell simulation problem using an unstructured grid on a real, faulted field case remains a challenge for two main reasons. First, the workflow typically used to construct and run the simulation problems has...

To perform this workflow, the engineer needs only to add the definition of the sector to the model, and the type of boundary condition to apply. As a square is chosen here, which passes through all layers of the model, the stacked contour S in Equation (2...
