Open source flow solver caffa3d.MBRi is applied in this work to solve the cases proposed in the SBC2012 CFD Challenge, offering an overall very cost effective solution. It is found that cycle-averaged pressure drops are well represented by correspoding stationary cases, while peak systole pressure drop values are widly overestimated by corresponding stationary cases.

The capability of wave generation and absorption in a viscous flow solver becomes important for achieving realistic simulations in naval and offshore fields. This study presents an efficient generation of nonlinear wave fields in the viscous flow solver by using a nonlinear potential solver called higher-order spectral method (HOS). The advantages of using a fully nonlinear potential solver for the generation of irregular waves are discussed. In particular, it is shown that the proposed method allows the CFD simulation to start at the time and over the space of interest, retrieved from the potential flow solution. The viscous flow solver is based on the open source library OpenFOAM. The potential solvers used to generate waves are the open source solvers HOS-Ocean and HOS-NWT (Numerical Wave Tank). Several simulation parameters in the CFD solver are investigated in the present study. A HOS wrapper program is newly developed to regenerate wave fields in the viscous flow solver. The wrapper program is validated with OpenFOAM for 2D and 3D regular and irregular waves using relaxation zones. Finally, the extreme waves corresponding to the 1000 year return period condition in the Gulf of Mexico are simulated with the viscous flow solver and the wave elevation is compared with the experiments.

What are the requirements for the Wiki engines to be used collaborative learning activities? Can any general-purpose engine be used? Or is there a niche for an educationally oriented crop of wiki engines? Do these educational wikis need to be integrated within the LMS to frame the collaborative activity within the walls of the virtual classroom, or is it preferable to have an external engine? These questions arise to every teacher who is about to plan a wiki-based collaborative learning activity. In this paper, the authors examine the use of wikis in college courses at three universities. The findings of this research are introduced and adopted as new features in two major open source wiki engines used for education: the Wiki module for Moodle 2.0 (as a Wiki engine embedded inside a LMS) and Tiki as independent full-featured Wiki CMS/Groupware engine.

Open source software (OSS) has gained considerable attention recently in healthcare. Yet, how and why OSS is being adopted within hospitals in particular remains a poorly understood issue. This research attempts to further this understanding. A mixed-method research approach was used to explore the extent of OSS adoption in hospitals as well as the factors facilitating and inhibiting adoption. The findings suggest a very limited adoption of OSS in hospitals. Hospitals tend to adopt general-purpose instead of domain-specific OSS. We found that software vendors are the critical factor facilitating the adoption of OSS in hospitals. Conversely, lack of in-house development as well as a perceived lack of security, quality, and accountability of OSS products were factors inhibiting adoption. An empirical model is presented to illustrate the factors facilitating and inhibiting the adoption of OSS in hospitals.
