ReFRESCO-Research vs ReFRESCO-Operation

ReFRESCO is an community-based open-usage and open-source code. This means that only members of these community can use and develop the code. While all members can modify the code for their purposes, all developments go into the production code and are shared within all partners. There is only one code! and quality control is enforced […]

Numerical Uncertainty Tools Available

In order to improve the reliability and acceptability of any CFD calculation,  a CFD result should be always accompanied of an uncertainty bar.  Within ReFRESCO community since the beginning we have used code verification, solution verification, solution validation techniques (or usually called V&V techniques). And we have put lots of effort on pushing the usage of these techniques […]

Workshop on Estimation of Discretization Errors Based on Grid Refinement Studies

Not one but rather two workshops on V&V will be organized by IST/MARIN next year May 2017, in LasVegas, Nevada, USA,under the ASME V&V 20 Committee activities. MARIN and IST will be organizing it and also participating with results obtained with ReFRESCO. While the first workshop deals with the influence of iterative error (and statistical error) on […]

ReFRESCO@TexasA&M USA

Last end of May, ReFRESCO has been installed in the clusters of Texas A&M University, College Station, USA. Also, an introductory course has been given to some interested Msc, Phd, Post-docs and staff members of TAMU. And a general presentation on the past, present and future of ReFRESCO has also been done. We expect a very […]

CFD Courses for Maritime Applications@MARIN NL

MARIN will host a new CFD course for Maritime Applications at its Wageningen headquarters,  November 14 – 17. This course has been designed to reflect the latest developments in Computational Fluid Dynamics (CFD) used in ship design, offshore engineering and renewable energy applications. The new course will examine how to obtain reliable and accurate CFD […]

New (more flexible) deployment policy

From this year on, ReFRESCO deployment policy will be changed. Due to the fast development, but also critical demands from our users :-), we will now consider the following rules: deploy beta versions (ex: refresco/2.3.0-b1) where new features are incorporated. These will be tagged in svn and deployed to all users (internal and external!); two […]

CFD Simulations on Anti-Roll Tanks (ARTs). Article at MarineLink.com magazine

A new article on ReFRESCO CFD simulations for the analysis of anti-roll tanks (ART) has been published online at MarineLink.com (work done back in 2014). The ReFRESCO results of the U-shaped ART have been compared with available CFD and experimental results from literature, as well as with MARIN’s own experiments, using the MARIN Anti-Roll Tank Facility.

Survival of the Fittest (CFD codes)…

Super-computers are about to change the virtual world in which computational fluid dynamics exists. James Hawkes (Phd of University of Southampton and Marin Academy) goes exploring and describes the changes that will revolutionise vessel design in his article at the Naval Architect, issue of July/August 2015. Here an excerpt related with his ReFRESCO work: “… Work is […]

Verification and Validation (V&V) @ MARIN-Academy/IST using ReFRESCO

Like in previous years, MARIN-Academy and IST was present in the most important worldwide symposium on Verification & Validation. Prof. Luis Eca representing both institutions gave two presentations on “Verification of Solutions in Unsteady Flows” and “An Example of Application of a Multivariate Metric based on Multiple Validation Set Points” using ReFRESCO (check here for both papers).

A new PhD thesis using ReFRESCO

Last June, Guilherme Rosetti from University of Sao Paulo, Brasil has defended his Phd thesis entitled: “Improvements in the Numerical Modeling of Turbulence and Fluid-Structure Interaction for the Vortex-Induced Vibrations of a Rigid Cylinder”. Supervised by Guilherme Vaz from MARIN and Andre Fujarra from USP, Guilherme has been working on turbulence, transition and (rigid body) Fluid-Structure-Interaction (FSI) for the […]

New MarinReport number only on CFD and with lots of ReFRESCO…

The new MARIN magazine “MarinReport” has been published. This numbers goes only about CFD. And of course there is a lot on ReFRESCO: usage by external partners, application examples, verification and validation studies, and even an overview article on the past, present and the future of ReFRESCO. It is also interesting to read the (actual) […]
