Ansys, Inc. is an American multinational company with its headquarters based in Canonsburg, Pennsylvania. It develops and markets CAE / multiphysics engineering simulation software for product design, testing and operation and offers its products and services to customers worldwide.
The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at discrete points called nodes.
Random vibration. In mechanical engineering, random vibration is motion which is non-deterministic, meaning that future behavior cannot be precisely predicted. The randomness is a characteristic of the excitation or input, not the mode shapes or natural frequencies. Some common examples include an automobile riding on a rough road, wave height ...
Contents. Geometric modeling kernel. A geometric modeling kernel is a solid modeling software component used in computer-aided design (CAD) packages. [ 1 ][ 2 ] Available modelling kernels include: ACIS is developed and licensed by Spatial Corporation of Dassault Systèmes. SMLib is developed by Solid Modeling Solutions.
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [ 1 ] It is one of the oldest and broadest of the engineering branches.
The Level-set method (LSM) is a conceptual framework for using level sets as a tool for numerical analysis of surfaces and shapes. LSM can perform numerical computations involving curves and surfaces on a fixed Cartesian grid without having to parameterize these objects. [1] LSM makes it easier to perform computations on shapes with sharp ...
Ansys HFSS. Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit ...
It defines a family of tensors, which describe the configuration of the body in either the current or the reference state. The first Piola–Kirchhoff stress tensor, , relates forces in the present ("spatial") configuration with areas in the reference ("material") configuration. where is the deformation gradient and is the Jacobian determinant.
