This code base contains PyTorch implementations of graph neural networks for CFD simulation surrogate development. The plan is to apply this code to predict volume fraction fields associated with CFD simulations of a representative column model (Fu et al., 2020) for solvent-based carbon capture within the CCSI2 project.
