What are the solvers in OpenFOAM?

The current list of solvers distributed with OpenFOAM is given in the following Sections.

  • 1 ‘Basic’ CFD codes. laplacianFoam.
  • 2 Incompressible flow.
  • 3 Compressible flow.
  • 4 Multiphase flow.
  • 5 Direct numerical simulation (DNS)
  • 6 Combustion.
  • 7 Heat transfer and buoyancy-driven flows.
  • 8 Particle-tracking flows.

Is OpenFOAM accurate?

OpenFOAM contains a number of solvers [4-7] having different computational properties. Presented in a tabular form solutions [8] have high accuracy and for many years are used for test- ing the computational properties of numerical methods.

What is smooth solver in OpenFOAM?

Smoother is another name for sparse linear solver like Jacobi, Gauss Seidel and all. It is called smoother because we do not use this to solve the linear system but rather quickly remove some part of error. Other than Jacobi, openfoam also uses ILU based smoother. keepfit, minh khang, tonnykz and 1 others like this.

What is GAMG in OpenFOAM?

• GAMG/ – Geometric agglomerated algebraic multigrid solver (also named Generalised geometric- algebraic multi-grid in the manual)

What is Rhopimplefoam?

rhoSimpleFoam is a steady-state solver for compressible, turbulent flow, using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm. It is a pressure based compressible solver. That means that a pressure equation is solved and the density is related to the pressure via an equation of state.

What language is OpenFOAM?

C++
C++, however, possesses all these features while having the additional advantage that it is widely used with a standard specification so that reliable compilers are available that produce efficient executables. It is therefore the primary language of OpenFOAM.

Is OpenFOAM used in industry?

OpenFOAM is a free and open source CFD toolbox. OpenFOAM stands for Open source Field Operation And Manipulation. It is used in academia and industry to solve wide variety of computational problems.

What is Pimple algorithm?

The PIMPLE Algorithm is a combination of PISO (Pressure Implicit with Splitting of Operator) and SIMPLE (Semi-Implicit Method for Pressure-Linked Equations). All these algorithms are iterative solvers but PISO and PIMPLE are both used for transient cases whereas SIMPLE is used for steady-state cases.

What is SimpleFoam?

SimpleFoam is a steady-state solver for incompressible, turbulent flow, using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) algorithm. In the newer releases it also includes an option to use the SIMPLEC (Semi-Implicit Method for Pressure Linked Equations Consistent) algorithm.

Is OpenFOAM easy?

OpenFOAM is really a great CFD software. It is easy to get, but the price you pay is a time you spend on learning it. This price is always higher than expected in the first place. If succeeded the value you get is huge.

Where can I find the solvers with the OpenFOAM distribution?

The solvers with the OpenFOAM distribution are in the $FOAM_SOLVERS directory, reached quickly by typing sol at the command line. This directory is further subdivided into several directories by category of continuum mechanics, e.g. incompressible flow, combustion and solid body stress analysis.

How do I use OpenFOAM to solve CFD problems?

The OpenFOAM control panel and solver settings dialog box allows one to use OpenFOAM to solve CFD problems. In the lower control button panel the Solve button will start the automatic solution process with the chosen settings. This means that the following steps are performed in sequence

What is OpenFOAM used for?

The OpenFOAM code base is widely used in academia, as well as in industry by for example Volkswagen and Audi in automotive engineering applications [ 1,2 ], and in Formula 1 racing to model and optimize aerodynamics [ 3,4 ].

How do I verify that OpenFOAM is installed with FEATool?

Verification Select System Info… from the Help menu to verify that the OpenFOAM installation can be found by FEATool. This will open a dialog box with details for the current system and FEATool configuration. Find the line item labeled OpenFOAM: and verify that it points to your OpenFOAM installation folder, for example
