The paper demonstrates the model order reduction procedures applied to semiconductor devices with multiple heat sources. The approach is demonstrated for a device with nine heat sources where some of them are permanently active and other work under switching conditions. For the order reduction the software package MOR for ANSYS is used, which is based on the Krylov subspace method via the Arnol...

Analytical and numerical solutions are presented for viscoelastic lifting surfaces with piezoelectric control devices. Computational protocols in terms of spatial finite elements and temporal finite differences are formulated. ANSYS is used for mesh generation and numerical solutions are carried out in ABAQUS. Because of lack of provisions in ABAQUS for displacement dependent forces (lift), add...

COMPUTATIONAL FLUID DYNAMICS has been adopt-e d b y m a n y industries to provide a better understanding of countless applications. New and unusual uses for the technology continue to appear, as evi-denced by our cover story on archaeological analysis (page 5). While the extent of an ancient municipal water system in Syria was unearthed by excavation, the clever-ness of the hydraulic engineers ...

This article attempts to examine acoustic finite element analysis coupled with structure, and provides the necessary information to apply ANSYS for a wide class of structural acoustics problem. First part of this article describes the acoustic field and hence the uses of acoustic point sources in ANSYS. Results are explained and compared with that of analytical solution. And second part deals w...

Firstly this article briefly describes the technology of topology optimization. Then the design space of frame of aircraft deicing vehicle is established and the model of finite element is gained by meshing. Loads and DOF constraints are applied based on the analysis of working conditions. The results of topology optimization are attained by calculation. On the basis of aforementioned results, ...

As hardware accelerators and especially GPUs become more and more popular to accelerate the compute intensive parts of an algorithm, standard high performance computing packages are starting to benefit from this trend. We present the first GPU acceleration of the ANSYS direct sparse solver. We explain how such a multifrontal solver may be accelerated using an optimized dense matrix factorizatio...

The basic concept of dynamic characteristics of spindle is introduced. The first ten order vibration mode and natural frequency of shaft are obtained by modal analysis and harmonic response analysis using software ANSYS. The deformation trend of spindle under resonance state is analysed and the contrast between theory and simulation critical speed is done. The frequency response curve of spindl...
