“…Typical examples include volumetric CT/MRI/MRA data, computational fluid dynamics data, and finite element solutions to bioelectric field problems. Recent research has focused on diffusion tensor MRI and multimodal medical data such as fused MRI/EEG volumes [14]. These datasets range in size from megabytes to gigabytes and may be static or time-varying on a variety of grid types.…”

“…Compared with the post-processing model, this model provides a mechanism through which the user is able to control and manipulate the proceeding of the simulation and may then alter the processing steps as required. This process is continuous, dynamic and interactive (Hibbard, 1998;Johnson, 1999).…”

ABSTRACT. This paper introduces a novel visualization approach that can effectively facilitate the analysis, control, and refinement of dynamic environmental simulations on the World Wide Web. This approach overcomes drawbacks of current Internet Geographic Information System (GIS) technologies by providing an effective and efficient mechanism for two-way and sustained communication and synchronization between the visualization and the modeling processes. The critical aspect of this approach is the establishment of a virtual environment on the Internet using the applet-servlet-socket architecture that supports real-time interactive and collaborative visualization of an environmental modeling process. In this virtual environment, the model residing in the simulation application server is fed with real-time rainfall data from a remote data server through a socket connection. The computational modeling and visualization can take place simultaneously on the application server and the client sides. As modeling computations proceed on the server, modeling results and outputs stream into the client side continuously. The client interface is updated with live 3D displays (not in the sense of predefined 3D animations provided by AVI or dynamic GIF files). Meanwhile, these 3D graphics can act as a support for further user interactions. A hydrological model, TOPMODEL, is implemented using the proposed web-based visualization environment to demonstrate the applicability of the proposed approach in facilitating environmental modeling and simulation.

In this report is described the work effort to develop and demonstrate a software framework to support advanced process simulations to evaluate the performance of advanced power systems. Integrated into the framework are a broad range of models, analysis tools, and visualization methods that can be used for the plant evaluation. The framework provides a tightly integrated problem-solving environment, with plug-and-play functionality, and includes a hierarchy of models, ranging from fast running process models to detailed reacting CFD models. The framework places no inherent limitations on the type of physics that can be modeled, numerical techniques, or programming languages used to implement the equipment models, or the type or amount of data that can be exchanged between models. Tools are provided to analyze simulation results at multiple levels of detail, ranging from simple tabular outputs to advanced solution visualization methods. All models and tools communicate in a seamless manner. The framework can be coupled to other software frameworks that provide different modeling capabilities.Three software frameworks were developed during the course of the project. The first framework focused on simulating the performance of the DOE Low Emissions Boiler System Proof of Concept facility, an advanced pulverized-coal combustion-based power plant. The second framework targeted simulating the performance of an Integrated coal Gasification Combined Cycle -Fuel Cell Turbine (IGCC-FCT) plant configuration. The coal gasifier models included both CFD and process models for the commercially dominant systems. Interfacing models to the framework was performed using VES-Open, and tests were performed to demonstrate interfacing CAPE-Open compliant models to the framework. The IGCC-FCT framework was subsequently extended to support Virtual Engineering concepts in which plant configurations can be constructed and interrogated in a three-dimensional, user-centered, interactive, immersive environment. The Virtual Engineering Framework (VEF), in effect a prototype framework, was developed through close collaboration with NETL supported research teams from Iowa State University Virtual Reality Applications Center (ISU-VRAC) and Carnegie Mellon University (CMU). The VEF is open source, compatible across systems ranging from inexpensive desktop PCs to large-scale, immersive facilities and provides support for heterogeneous distributed computing of plant simulations. The ability to compute plant economics through an interface that coupled the CMU IECM tool to the VEF was demonstrated, and the ability to couple the VEF to Aspen Plus, a commercial flowsheet modeling tool, was demonstrated. Models were interfaced to the framework using VES-Open. Tests were performed for interfacing CAPE-Open-compliant models to the framework. Where available, the developed models and plant simulations have been benchmarked against data from the open literature. The VEF has been installed at NETL.The VEF provides simulation capabilities not availab...
