Abstract— We present a fast and straightforward Eulerian technique to simulate fluid flows on three-dimensional parameterized structured grids. The method’s primary design goal is the correct and efficient handling of fluid interactions with curved boundary walls and internal obstacles. This is accomplished by the use of per-cell Jacobian matrices to relate field derivatives in the world and parameter spaces, which allows us to solve the Navier-Stokes equations directly in the latter, where the domain discretization becomes a uniform grid. We describe how to apply Jacobian matrices to each step of a standard regular-grid-based simulator, including the solution of Poisson equations using both Jacobi iterations and a Biconjugate Gradient Stabilized sparse matrix solver. The technique is implemented efficiently in the CUDA programming language and takes full advantage of the massively parallel architecture of graphics cards.

Abstract - In teaching medical decision-making, comprehensive training simulators are of great importance.

These must include models of various physiological subsystems, and also integrate them into a comprehensive whole. Medical simulators have recently become a highly sought-after commercial commodity. Like an airline pilot simulator, a medical simulator is controlled by a remote operator, who manipulates the simulated patient and chooses between various scenarios to simulate different maladies. The core of a medical training simulator is a complex model of the human body‘s internal physiological regulators, connected with a hardware simulator. Its detailed structure (the system of equations and the parameter values that feed into them) is usually not published, becoming a carefully-protected piece of trade secrets There are also open source models of integrated physiological systems. One is a large model by Coleman et al. called HumMod (http://hummod.org) implemented by thousands of XML files. Our implementation of this model in the Modelica language has brought a much easier description of the simulated complex physiological relationships than XML implementation. We uncovered several mistakes in the original model, and we have modified and expanded the original model (particularly in modelling acid-base homeostasis). Our new model is called HumMod – Golem Edition (http://physiome.cz/ hummod), and will provide a new theoretical basis for medical training simulator. In its implementation we will use our web simulator creation technology.

1 Introduction

During the past decade there have been a number of attempts to use computers to enhance building design education. The target audiences for these software tools have been architecture, building construction, and engineering students (Messner and Horman [1]; Moloney and Amor [2]; Sulbaran and Crosby [3]; Kalisperis, et. al.
