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 the […]

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 months prior […]

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 currently […]
