Water Flowing Over a Dam

Software

Rizea Engineering conducts our CFD analysis using OpenFOAM. OpenFOAM is an open-source CFD solver widely deployed in both commercial and academic arenas. The open-source approach offers numerous advantages over commercial codes:

 

• The source code can be modified to adapt to specific applications - improve convergence speed and stability
• The solver can be packaged with custom parameters and GUI - let designers without CFD expertise leverage OpenFOAM in their work
• Direct control over accuracy parameters - commercial codes can compromise accuracy in the name of convergence stability
• Readily scalable - we can add local or cloud-based computing power without the need to purchase additional node licenses
• An extensive library of validation cases in published academic literature

 

As with any modern CFD code, OpenFOAM is continually validated and verified, and it can tackle a wide range of problems:

 

• Incompressible Flow
• Compressible Flow
• Multiphase Flow (Including Free Surface)
• Phase Change
• Combustion
• Fluid-structure Interaction
