Addressing A Posteriori Performance Degradation in Neural Network Subgrid Stress Models
Andy Wu, Sanjiva K. Lele
Neural network subgrid stress models often have a priori performance that is far better than the a posteriori performance, leading to neural network models that look very promising…

Subgrid Stress Modelling with Multi-dimensional State Space Sequence Models
Andy Wu, Sanjiva K. Lele
Large Eddy Simulations (LES) are becoming increasingly viable due to the growth in computational power the last few decades, and subgrid stress modelling plays a large role in the…
