scaleupROM is a projection-based reduced order model (ROM) with discontinuous Galerkin domain decomposition (DG-DD). It aims to construct a robust, efficient, large-scale ROM that is trained only from small scale component samples, for various physics partial differential equations. scaleupROM is mainly built upon MFEM and libROM.
- Discontinuous Galerkin domain decomposition
- Projection-based reduced order model
- EQP for nonlinear partial differential equations
- Supporting physics equations:
- Poisson equation
- Stokes flow
- Steady Navier-Stokes flow
- Linear elasticity
- Nonlinear elasticity
- Time-dependent Navier-Stokes flow
See the wiki page for the detailed instruction.
