Unstructured Grid

We have developed and implemented an element-based finite volume (EbFV) method for unstructured grids using mixed elements. The EbFV method has been implemented and tested in both GPAS and UTCHEM. Initial results of the EbFV method in UTCHEM show that the new implementation can better capture the reservoir geometry compared to the finite difference discretization method. Further enhancement and validation of the EbFV method is under progress.
