mdFoam: Advanced molecular dynamics in OpenFOAM [PDF]
Computer Physics Communications, 2018 This paper introduces mdFoam+, which is an MPI parallelised molecular dynamics (MD) solver implemented entirely within the OpenFOAM software framework. It is open-source and released under the same GNU General Public License (GPL) as OpenFOAM. The source code is released as a publicly open software repository that includes detailed documentation and ...

Insertion of PETSc in the OpenFOAM Framework
ACM Transactions on Modeling and Performance Evaluation of Computing Systems, 2017OpenFOAM is a widely used open source framework for simulation in several areas of computational fluid dynamics and engineering. As a partial differential equation (PDE)-based framework, OpenFOAM suffers from a performance bottleneck in solving large-scale sparse linear systems of equations.

A Discrete Adjoint Model for OpenFOAM
Procedia Computer Science, 2013 AbstractWe present a discrete adjoint version of the open-source fluid-dynamics package OpenFOAM obtained by operator overloading which yields, in comparison to continuous adjoint versions, a greater flexibility and robustness. We discuss our implementation and how the discrete adjoint version of OpenFOAM differs from existing continuous ...

Harmonic Balance developments in OpenFOAM
Computers & Fluids, 2018The Harmonic Balance method for simulating unsteady nonlinear periodic flows is presented in this pa- per. Its recent, yet rapid development was motivated by the possibility of significant CPU time consump- tion savings compared to conventional transient methods, while providing sufficient accuracy.

Calculation of a Ventilated Cavity in OpenFOAM
Topical Problems of Fluid Mechanics 2023, 2023In this paper the formation of a cavity behind a streamlined body under the regime of air injection into a water flow in the gravity field is studied. Mathematical modeling is based on the Volume of Fluid method. The determining system of equations for the water-air mixture consists of the Navier-Stokes equation, continuity, conservation of energy, and

Application of PETSc in the Linear Solver of OpenFOAM
2015 IEEE 12th Intl Conf on Ubiquitous Intelligence and Computing and 2015 IEEE 12th Intl Conf on Autonomic and Trusted Computing and 2015 IEEE 15th Intl Conf on Scalable Computing and Communications and Its Associated Workshops (UIC-ATC-ScalCom), 2015Open FOAM is an open-source CFD software based on finite volume method. Due to the well-designed framework, it is widely used in various fields. However, the linear system of Open FOAM is tightly coupled with the discretization grid, which brings great difficulties in extending this platform. After analyzing the discrete and linear systems of Open FOAM,
