Interface Capturing in OpenFOAM

Interface Capturing in OpenFOAM

In July 2020, CFD Direct released a framework for surface interpolation in interface capturing for multiphase flows in OpenFOAM. All interpolation schemes, used for flux calculation in advection, operate with the MULES-based solvers, e.g. interFoam. The framework is easy to use, extensible, and robust due to bounded, conservative numerics. The new framework comes with a new family of interpolation schemes based on piecewise-linear interface calculation (PLIC). The PLIC schemes provide a promising alternative to standard interface compression, performing better for meshes with regions of cell refinement. All schemes are conservative, bounded and robust and can run efficiently with large time steps.

CFD Direct Year 5: 2019-2020

In Year 5 of CFD Direct, we developed new functionality in OpenFOAM and maintained critical components of the code base. We managed the OpenFOAM Foundation: promoting sustainable development, releasing OpenFOAM v7, packaging OpenFOAM-dev and publishing websites and documentation. We delivered 60 days of OpenFOAM Training, and provided low-cost cloud CFD with CFD Direct From the Cloud™ to over 500 subscribers, including custom images to run 100s of automated production simulations.

Maintaining a CFD Capability

Maintaining a CFD Capability

Your organisation has an expert in CFD with OpenFOAM. They deliver critical results to problems no one else can solve. They have worked there as long as you can remember. Then one day they announce they are leaving and years of experience and know-how walks out of the door. “That-person-left syndrome”, as we call it, is a failure in maintenance which CFD Direct can help with. We provide development, support, training and cloud services to limit the impact of that-person-left syndrome, building a sustainable CFD capability for our customers with OpenFOAM.
