Mesh Confidently Using Pointwise for CFD Generating meshes for computational fluid dynamics is neither easy nor fun. But mesh generation is where you have the most direct influence on how fast, how converged and how accurate your CFD solutions is. Because of that, you need a mesher that\’s flexible, robust and reliable. That\’s Pointwise.How Meshing is Better with PointwiseQuality Mesh quality is the key to converged and accurate CFD solutions especially for viscous flows over complex geometry. With Pointwise, you get all the tools you need to achieve the desired results – high levels of automation plus intimate levels of control. Pointwise\’s structured quad/hex grid techniques are the best available and our T-Rex technique for hybrid prism/tet meshes automates the...

HEXPRESS™/Hybrid is the latest of NUMECA\’s meshing tools designed for meshing complex geometries starting from unclean CAD data.HEXPRESS™/Hybrid is the latest of NUMECA\’s meshing tools designed for meshing complex geometries starting from unclean CAD data. The tool produces unstructured hex-dominant conformal meshes in parallel, including high quality viscous layers. The integrated automatic wrapping technology and the HoleSearcher allow the user to avoid the time spent on CAD cleaning and repairing, thus significantly reducing the engineering time spent on the generation of a mesh. This enables the user to obtain a mesh in a matter of hours instead of days/weeks.The general nature of HEXPRESS™/Hybrid makes it applicable in a wide variety of industries: Automotive: early design, external aerodynamics, thermal management and...

Scalable solutions for spot-on sound testing and analysis LR 02.jpg Acoustic testingProduct sound and sound quality are key aspects of product perception. How a product sounds plays a critical role in conveying the right message about its functionality, comfort, overall brand image and its quality. Regulations and competitive pressure have forced manufacturers to keep noise levels within limits and meet increasingly stringent sound standards. Structural testingStructural testing used to be a long and complex process involving quite extensive trial-and-error and time-consuming test setups. This is no longer the case. With LMS Test.Lab Structures and the LMS SCADAS system, test engineers perform large-scale modal surveys in hours rather than days. They can focus on identifying root causes of vibration problems and...
