FE-project

What is this project?

In FE-Project, we develop a library for fluid simulations with the discontinuous Galerkin method (DGM). We also provide sample programs and atmospheric models for meteorological simulations.

  • Example of simulation results by nonhydrostatic atmospheric models with nodal DGM

A simulation of density current

A simulation of idealized baroclinic instability
