About realization of one-dimensional quasi-gas dynamic algorithm in the open program OpenFOAM complex
Abstract:
An example of including a quasi-gas-dynamic algorithm in the OpenFOAM open-source software package is given. Advantages of OpenFoam are user orientation, separation of concepts of geometry, calculation area, choice of basic equations descretization and visualization of main results. The QGDFoam solver was tested on one-dimensional characteristic tests on breakdowns of discontinuities. A comparison of solutions is made using QGDFoam and the built-in solver of rhoCentralFoam. The QGDFoam versions are publicly available on the
http://github.com/unicfdlab/QGDsolver/.
