Industrial Fluid Properties Simulation Challenge
Introduction and Goals
The Industrial Fluid Properties Simulation Challenge is an open competition with the goals of driving improvements in the practice of molecular modeling, formalize methods for the evaluation and validation of simulation results with experimental data, and ensure relevance of simulation activities to industrial requirements. The Simulation Challenge was initiated by the workshop on "Predicting the Thermophysical Properties of Fluids by Molecular Simulation" (link) and is part of the overall vision of the Industrial Fluid Properties Simulation Collective.
