NX Nastran solves structural analysis problems for linear and nonlinear analysis, dynamic response, rotor dynamics, aeroelasticity and optimization. The NX Nastran 9.1 release further increases the types of solutions you can perform, along with a number of computational performance and engineering workflow improvements as highlighted by the examples below:Discipline and Physical Domain ExtensionNX 9.1 – Simulation – Nastran – Discipline and Physical Domain ExtensionSpeed-dependent bearing properties for rotor dynamics allow you to more realistically simulate bearings in rotating systems, such as aircraft engines. Properties of the bearing are speed-dependent and support the inherent cross-directional coupling stiffness and viscous damping.Greater flexibility to model multi-rotor systems allows you to describe speeds of all rotors independently. This means you can model multiple rotors...

FEMFAT (Finite Element Method Fatigue) is the number one engineering software tool for fatigue life prediction. It is used to improve reliability and robustness of components in automotive and machinery industry. FEMFAT is a tool designed to identify critical locations and supports the light weight optimization process at an early development stage, way before time- and cost-consuming tests will be performed. This results in high confident level to release prototypes, therefore less development loops and costly hardware tests. Continuously developed over the last 20 years, FEMFAT provides reliable results to release virtual prototypes in an early development stage. FEMFAT is widely used in the automotive and non-automotive industry and trusted to be the number one tool for CAE. The binding...

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...
