Synopsis
ITHACA-SEM: In real Time Highly Advanced Computational Applications with Spectral Element Methods - Reduced Order Models for Nektar++ , is a C++ package for the Model Order Reduction that uses simulations from the spectral/hp element software Nektar++. It uses Eigen to perform the matrix decompositions required for parametric model order reduction. The GitHub repository is available here: ITHACA-SEM.
Requirements
The requirement is an installation of Nektar++ in version 4.4.0.
Features
As of Feb. 2019:
- currently limited to steady-state Navier-Stokes solutions
- allows using a variable Reynolds number (specified by the kinematic viscosity) as parameter
- perform offline simulation in ITHACA-SEM or use precomputed Nektar++ *.fld files as snapshot solutions
- computes a POD ROM
- computes ROM parameter sweeps
