The goal of this integration was to add the Grid-functionalities of the Globus Toolkit to the existing TENT solutions for resource selection, application starting and data transfer, and in some cases to replace them entirely. A major advantage of this integration is that it allows TENT to use the security mechanisms in Globus. Globus integration turns TENT into a grid computing environment, i.e. an application that gives users access to the resources of computational grids for their daily work.
Globus Toolkit features were added to TENT in these areas:
Objective and description
The objective of the IMENS project was the development of a simulation environment for the coupled flow structure analysis of hermally stressed components of re-entry vehicles.
On the flow side, CFD solver TAU+ (from DLR) and DAVIS-VOL (a development of EADS) are used for the coupled simulation. ANSYS or MSC/NASTRAN are used for structure calculation. Both thermal and mechanical stresses are taken into account. Due to the different requirements for the linkage, TAU+ was integrated with a TAU+ co-process developed by the Institute of Aerodynamics and Flow Technology. An ANSYS >co-process was also developed. ANSYS permits extraction of the data relevant for coupling via a script cache, making this co-process considerably easier to implement than the NASTRAN co-process, for which the co-process must analyze input and output data completely syntactically and semantically).
