NUNet: Deep Learning for Non-Uniform Super-Resolution of Turbulent Flows

no code implementations26 Mar 2022 Octavi Obiols-Sales, Abhinav Vishnu, Nicholas Malaya, Aparna Chandramowlishwaran

Due to NUNet's ability to super-resolve only regions of interest, it predicts the same target 1024x1024 spatial resolution 7-28. 5x faster than state-of-the-art DL methods and reduces the memory usage by 4. 4-7. 65x, showcasing improved scalability.

SURFNet: Super-resolution of Turbulent Flows with Transfer Learning using Small Datasets

no code implementations17 Aug 2021 Octavi Obiols-Sales, Abhinav Vishnu, Nicholas Malaya, Aparna Chandramowlishwaran

SURFNet primarily trains the DL model on low-resolution datasets and transfer learns the model on a handful of high-resolution flow problems - accelerating the traditional numerical solver independent of the input size.

Mosaic Flows: A Transferable Deep Learning Framework for Solving PDEs on Unseen Domains

no code implementations22 Apr 2021 Hengjie Wang, Robert Planas, Aparna Chandramowlishwaran, Ramin Bostanabad

Then, we proposed mosaic flow(MF) predictor, a novel iterative algorithm that assembles the GFNet's inferences for BVPs on large domains with unseen sizes/shapes and BCs while preserving the spatial regularity of the solution.

Brief Announcement: On the Limits of Parallelizing Convolutional Neural Networks on GPUs

no code implementations28 May 2020 Behnam Pourghassemi, Chenghao Zhang, Joo Hwan Lee, Aparna Chandramowlishwaran

However, popular deep learning (DL) frameworks such as TensorFlow and PyTorch launch the majority of neural network operations, especially convolutions, serially on GPUs and do not exploit this inter-op parallelism.

CFDNet: a deep learning-based accelerator for fluid simulations

no code implementations9 May 2020 Octavi Obiols-Sales, Abhinav Vishnu, Nicholas Malaya, Aparna Chandramowlishwaran

CFD is widely used in physical system design and optimization, where it is used to predict engineering quantities of interest, such as the lift on a plane wing or the drag on a motor vehicle.
