A unified understanding of scale-resolving simulations and near-wall modeling of turbulent flows using optimal finite element projections

Aniruddhe Pradhan, Karthik Duraisamy

The main objective of this work is to develop a unified framework that can be used as a lens to quantitatively assess and augment a wide range of coarse-grained models of turbulenc…

Conditionally Parameterized, Discretization-Aware Neural Networks for Mesh-Based Modeling of Physical Systems

Jiayang Xu, Aniruddhe Pradhan, Karthik Duraisamy

Simulations of complex physical systems are typically realized by discretizing partial differential equations (PDEs) on unstructured meshes. While neural networks have recently bee…

Arbitrary Order Solutions for the Eikonal Equation using a Discontinuous Galerkin Method

David Flad, Aniruddhe Pradhan, Scott Murman

We provide a method to compute the entropy-satisfying weak solution to the eikonal equation in an arbitrary-order polynomial space. The method uses an artificial viscosity approach…

Variational Multi-scale Super-resolution : A data-driven approach for reconstruction and predictive modeling of unresolved physics

Aniruddhe Pradhan, Karthik Duraisamy

The variational multiscale (VMS) formulation formally segregates the evolution of the coarse-scales from the fine-scales. VMS modeling requires the approximation of the impact of t…

Variational Multiscale Closures for Finite Element Discretizations Using the Mori-Zwanzig Approach

Aniruddhe Pradhan, Karthik Duraisamy

Simulation of multiscale problems remains a challenge due to the disparate range of spatial and temporal scales and the complex interaction between the resolved and unresolved scal…
