Physica : a Multiphysics Computational Framework and Its Application to Casting Simulations
نویسندگان
چکیده
Metals casting is a process governed by the interaction of a range of physical phenomena. Most Computational models of this process address only what are conventionally regarded as the primary phenomena-heat conduction and solidiication. However , to predict phenomena such as poros-ity requires modelling the interaction of the uid ow, heat transfer, solidiication and the development of stress-deformation in the solidiied part of the casting. This paper will describe a modelling framework called PHYSICA which has the capability to simulate such multiphysics based phenomena.

Application of M3GM in a Petroleum Reservoir Simulation
Reservoir formations exhibit a wide range of heterogeneity from micro to macro scales. A simulation that involves all of these data is highly time consuming or almost impossible; hence, a new method is needed to meet the computational cost. Moreover, the deformations of the reservoir are important not only to protect the uppermost equipment but also to simulate fluid pattern and petroleum produ...

High-fidelity coupled multiphysics simulations are an increasingly important aspect of computational science. In many domains, however, there has been very limited experience with simulations of this sort, therefore research in coupled multiphysics often requires computational frameworks with significant flexibility to respond to the changing directions of the physics and mathematics. This pape...
متن کاملSIERRA Framework Version 3: Core Services Theory and Design
The SIERRA Framework core services provide essential services for managing the mesh data structure, computational fields, and physics models of an application. An application using these services will supply a set of physics models, define the computational fields that are required by those models, and define the mesh upon which its physics models operate. The SIERRA Framework then manages all ...
