Physics-informed neural network (PINN) for solving fluid dynamics problems

Reference paper

This repo include the implementation of mixed-form physics-informed neural networks in paper:

Chengping Rao, Hao Sun and Yang Liu. Physics-informed deep learning for incompressible laminar flows.

This paper has been published by TAML, those who has access to Elsevier database can refer to https://www.sciencedirect.com/science/article/pii/S2095034920300350 for camera-ready version.

Description for each folder
