VERSATILE SOLVER, TAILORED FOR MARITIME CHALLENGES
ReFRESCO is a multi-phase viscous flow solver focused on maritime applications. Under active development by MARIN experts and multiple partners around the world, ReFRESCO is constantly evolving to better suit the evolving needs of the maritime world. Thorough code verification is performed for all releases of ReFRESCO, using our freely available Verification & Validation tools. The roadmap and long term strategy is coordinated by MARIN. The solver is suited for production simulations as well as for research. An additional toolkit is available for automated and easy setup and monitoring of simulations, making it easier to use for both CFD engineers and researchers. MARIN's knowledge and needs are used to improve these tools.
Features
ReFRESCO is based on the finite volume formulation and can work all types of cells, making it compatible with a wide variety of grid generation packages. Adaptive grid refinement capabilities help further with focusing the cells and computational resources at the crucial locations. Structures' motions can be either prescribed or solved with the built-in rigid body motion solver. Moving, sliding and deforming grid approaches are readily available to give high setup flexibility. In addition, overset grid capabilities are under active development.
Various turbulence models, from RANS models to high fidelity hybrid and scale resolving models, complemented with transition models are available to answer the most common maritime engineering challenges. Since we focus on maritime applications, ReFRESCO also features wave generation capabilities, dedicated propeller body-force models, acoustic models for underwater radiated noise, and couplings to externals tools such as fast time-domain simulation frameworks.

applications
Ship resistance
Resistance predictions with multi-phase simulations including free surface, or form-factor determination using single phase double-body simulations are parts of the mainstream applications.

Propulsion
Propeller performance in open-water or in-behind, at full scale or model scale can be predicted. Cavitation and acoustics model are also available for advanced studies.

motions and forces in waves
Motions and forces in waves can be evaluated thanks to the easy to use wave boundary conditions and the wave restoring zones available in the solver.

Refresco Participation
For partners willing to collaborate with us and use ReFRESCO, we propose three flexible frameworks. Participation in any of the frameworks comes with an unlimited number of parallel users, cpu cores and parallel computations. Access to our calcultion facility can also be arranged to run challenging cases in a reliable way.
The ReFRESCO Research framework can be joined for free. This framework is aimed towards public research where the results can be openly shared. Access to the source-code is possible for people who explicitely need to develop new features.
ReFRESCO-Operation is a paid framework within which partners can use the code for commercial application. We provide access to the solver, our best-pratice guidelines, our tools and provide support to our partners against a yearly fee.
ReFRESCO-Pro enables partners to have access to the solver on a monthly basis per project. This is made for partners who do not need full time access to a CFD solver, but want to perform CFD on their own.
