Multiscale modeling and interoperability in MOOSE

Modeling and Realizing Interoperability

Interoperability between enterprise applications requires an understanding of the obstacles to interoperability in order to provide methods for overcoming these obstacles. We address the problem from different angles: first, we investigate the benefit of multi-lingual ontologies to overcome language problems between users of an enterprise application. Second, we propose a method to integrate le...

Multiscale modeling

Multiname and Multiscale Default Modeling

Multiname default modeling is crucial in the context of pricing credit derivatives such as Collaterized Debt Obligations (CDOs). We consider here a simple reduced form approach for multiname defaults based on the Vasicek or Ornstein-Uhlenbeck model for the hazard rates of the underlying names. We analyze the impact of volatility time scales on the default distribution and CDO prices. We demonst...

Multiscale modeling methods in biomechanics

More and more frequently, computational biomechanics deals with problems where the portion of physical reality to be modeled spans over such a large range of spatial and temporal dimensions, that it is impossible to represent it as a single space-time continuum. We are forced to consider multiple space-time continua, each representing the phenomenon of interest at a characteristic space-time sc...

Multiscale Computing with the Multiscale Modeling Library and Runtime Environment

We introduce a software tool to simulate multiscale models: the Multiscale Coupling Library and Environment 2 (MUSCLE 2). MUSCLE 2 is a component-based modeling tool inspired by the multiscale modeling and simulation framework, with an easy-to-use API which supports Java, C++, C, and Fortran. We present MUSCLE 2’s runtime features, such as its distributed computing capabilities, and its benefit...
