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: - 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
