Modeling the dynamics of PDE systems with physics-constrained deep auto-regressive networks

•Deep auto-regressive dense encoder-decoder surrogate for predicting transient PDEs.•Physics-constrained learning enables the model to learn dynamics without training data.•A Bayesian framework is proposed for interpretable uncertainty quantification of the models' predictions at each time-step...
