Synopsis
ITHACA-FV is an implementation in OpenFOAM of several reduced order modelling techniques. ITHACA-FV is designed for OpenFOAM 6.0 and OpenFOAM 5.0 but it can be easily adapted also to other versions of OpenFOAM.
ITHACA-FV can also be used as a basis for more advanced projects that would like to assess the capability of reduced order models in their existing OpenFOAM-based software, thanks to the availability of several reduced order methods and algorithms.
Linear and non-linear algebra operations which are not already implemented in OpenFOAM are performed with the external library Eigen. The source code of Eigen 3.3.4 is provided together with ITHACA-FV and is located in the src/thirdyparty/Eigen. For the EigenValue decomposition it is also possible to rely on the Spectra-0.6.1 library and the source code is provided in the src/thirdyparty/spectra-0.6.1 folder.
ITHACA-FV has been tested on Ubuntu 16.04, Centos 6.6, Centos 7 and ArchLinux, but can be easily compiled on any linux distribution with a compiled version of OpenFOAM 6.0 or OpenFOAM 5.0.
Requirements
ITHACA-FV requires
Features
As of Feb. 2019:
- It can perform Linear and Non-Linear Model Order Reduction.
- Allows using generic parametrization specified by the user.
- It uses POD for the generation of the bases.
- Computes a POD-Galerkin reduced order model.
- Possibility to use non-intrusive POD-I methods with Radial Basis Function Interpolation.
- Discrete Empirical Interpolation Method for non-linearity and non-affinity.
