The technology refining experience of PWR fuel element units analysis is presented by the authors for some regimes of reactor functioning, that is necessary for technical designing. The principle possibility is shown and some examples are given as for solution of the following problems (using MSC MARC 2008 r1).

The stress and strain modeling is performed for perspective fuel elements produced by VNIINM for research reactors. The defined fuel element was selected from results of this modeling for further development and for testing at MIR research reactor conditions.

MSC Software and Sun Microsystems have worked together for two decades to optimize MSC's major applications, including MD Nastran, on Sun Systems. This talk will outline the recent collaboration between MSC.Software and Sun to more tightly integrate Sun Grid Engine and MD Nastran. The presentation will include a discussion of a recent series of "how-to" blogs on this integration effort (posted on Sun's blogs.sun site). The "how-to" blogs lay out in a step-by-step format how to configure Sun Grid Engine to work effectively with MD Nastran. Making use of MD Nastran's existing job queueing interface capabilities as well as MSC's resource estimation tool (the "ESTIMATE" program) this presentation will give an overview of how to configure typical SGE job queues for MD Nastran, submit serial and parallel jobs, and how to manage resource utilization (memory, disk space, and license tokens) to get optimum throughput on a compute cluster. The talk will also cover some "best practice" performance guidelines for running MD Nastran on Sun hardware.

Roland Dittel joined the Sun Grid Engine (SGE) engineering team at Sun Microsystems in 2005 after completing his degree in electrical engineering. Since this time he is responsible for the core modules of SGE and was involved in several projects and support cases. Roland designed and implemented the Resource Quota feature, Advance Reservation module, added improvements to software license management and contributed to scalability improvements for large and high throughput SGE clusters.

Among all manufacturing processes, hot metal forming takes a special place because of the relationship between microstructural changes and properties of the end product. Controlled thermomechanical influence, being an effective tool for generating defined microstructures, ensures high mechanical properties and is the base of Thermomechanical Treatment technologies. Simulation of such processes should be based on coupling of grain size evolution and phase transformation with thermoplastic deformation.

Wear is the main failure cause of PTFE-(Teflon) lip seals. They are used at shaft applications, whenever high temperatures, chemical resistance and/ or high circumferential speeds are required. Lip seals are cheap machine components but if they fail, they cause expensive machine down time. This could be minimized by simulating the wear of the lip seals. This presentation shows how to simulate the macroscopic wear process with MSC.Marc. The MSC.Marc rezoning features are used to reduce the volume of the finite element model. The solver is coupled with the NAG-Fortran-Libraries (Numerical Algorithm Group) to remesh the geometry if necessary. A phenomenological non-standard wear model is used to calculate the wear-height at each increment. The parameters of the wear model are measured at a ring on disc tribometer. The results of this simulation are the change of the geometry and the current contact normal stresses after an appointed running time or distance - the lifetime of PTFE-lip seals is computable. Furthermore a new approach is presented to use this method on top of a "bottom up", multi-scale wear model.

The extensometric observations are used to study the recent Earth crust deformations and recent geodynamic processes. Application possibilities are to analyse of natural effects caused by a wide spectrum of the Earth's physical processes and man-made effects. Monitoring of long period deformations of the Earth is usualy performed by extensometers of different constructions capable to measure of changes in 10-8 order. The instruments are usually placed in natural or artificial caves, underground galleries. The extensometric monitoring system of Geodynamical Observatory of the Eotvos Lorand Geophysical Institute (ELGI) is situated in a natural limeastone cave in Budapest. One of the most important factors influencing the accuracy of deformation measurements is the effect of the cavity system, distorting real deformations around the equipment. Rock body with cavities behaves differently than it would do filled with intact rock material. This makes the observation systems inhomogeneous in the sense of mechanical deformations. In our study the finite element modelling was used to estimate the order of influential effect in the complicated cavity system, surrounding the ELGI's observatory instruments. Auxiliary measurement results had been used for parameters in the modell definition. Geometry of the surface for the modelled terrain block is based on aerofotogrammetry data. On site seismic measurement had been performed to obtain in situ elastic parameters of limestones. Because the modell was loaded by a small 10exp(-8) strain, only the linear material behaviour was considered. Modelling calculations have revealed about 10% of cavity effect, which should be the subject of correction in the mechanical characteristics of the ELGI's extensometric system. The ideas of this paper by the same authors was presented on the CODATA-21 Conference (Kiev, Ukraine 4-8 October, 2008) and had been awarded as best poster of the conference.
