Synopsis

ithaca-sem box

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

References

ITHACA-SEM has been used in the following publications, i.e., either the c++ version or a previous python3 version, which is now listed under 'deprecated' in the GitHub repo.
