Datasets for "Robustness and Performance of the CPRW Preconditioner in Reservoir Simulation:A Theoretical and Experimental Study"

This repository contains eight benchmark datasets used to evaluate the CPRW preconditioner in large-scale reservoir simulations. The cases include synthetic and field-scale models with multiphase flow, thermal coupling, and strong well–reservoir interactions. All files are compatible with the OPM Flow simulator and support reproducible testing of solver robustness, convergence, and parallel scalability.
