weitere Infos  



Software package for explicit nonlinear structural simulation.

ANSYS LS-DYNA ist in die Hochschulversion von ANSYS integriert, d.h. Anzahl Knoten und Elemente sind begrenzt (maximale Anzahl Knoten: 128000; maximale Anzahl Elemente: 64000).

Die Schnittstelle "ANSYS Workbench for LS-DYNA" ist freigegeben und ab sofort verfügbar!

Was bedeutet das?
Typische explizite Aufgabenstellungen - große Deformationen, stark nichtlineares Materialverhalten oder kurzzeitdynamische Vorgänge, z.B. Falltestanalysen - können ab Version 11 in der gewohnten komfortablen ANSYS Workbench Umgebung aufbereitet, per Mausklick an LS-DYNA übergeben und dort berechnet werden. Über die reine Struktur hinaus werden Materialien, Kontaktdefinitionen, Randbedingungen sowie Verschiebungsgrößen- und Kraftvorgaben übertragen.

Kurzbeschreibung: englisch
ICEM CFD is used for engineering applications such as computational fluid dynamics and structural analysis. The grid generation tools offer the capability to parametrically create grids from geometry in multi-block structured, unstructured hexahedral, tetrahedral, hybrid grids consisting of hexahedral, tetrahedral, pyramidal and prismatic cells; and Cartesian grid formats combined with boundary conditions. Over 100 flow solver and structural analysis translators are provided to produce an input file containing mesh and boundary conditions. ICEM CFD also offers tools for post-processing and mesh optimization.

Kurzbeschreibung: englisch
Preprocessing is the first step in building and analyzing a flow model. It includes building the model (or importing from a CAD package), applying a mesh, and entering the data. There are two preprocessing tools, GAMBIT and TGrid.

GAMBIT CFD Preprocessor :
GAMBIT has a single interface for geometry creation and meshing that brings together all of Fluent's preprocessing technologies in one environment. Advanced tools for journaling let you edit and conveniently replay model building sessions for parametric studies. 
GAMBIT provides a concise and powerful set of solid modeling-based geometry tools. Top down geometry construction modeling-based geometry tools. Top down geometry construction using 3D primitives allows you to create geometries fast, without the complexity of a full-fledged CAD package. 
GAMBIT can import geometry from virtually any CAD/CAE software in Parasolid, ACIS, STEP, IGES, or STL format. 

TGrid CFD Preprocessor : 
TGrid performs advanced hybrid volume mesh generation using tetrahedra, pyramids, and prisms (wedges or hexahedra) and 2-D meshing with triangles and quadrilaterals. TGrid's robust, automated algorithms save preprocessing time and generate high-quality meshes for CFD analysis in FLUENT. 
Surface and volume meshes may be imported from GAMBIT, ANSYS, Catia, I-DEAS, NASTRAN, PATRAN, Pro/ENGINEER, Hypermesh, and more. Extensive tools are included for improving imported surface mesh quality and for rapidly assembling meshes from multiple parts.

After preprocessing, the CFD solver does the calculations and produces the results.
FLUENT uses unstructured meshes in order to reduce the amount of time you spend generating meshes, simplify the geometry modeling and mesh generation process,   model more-complex geometries than you can handle with conventional, multi-block structured meshes, and  let you adapt the mesh to resolve the flow-field features.   FLUENT can also use body-fitted, block-structured meshes (e.g., those used by FLUENT 4 and many other CFD solvers).  FLUENT is capable of handling triangular and quadrilateral elements (or a combination of the two) in 2D, and tetrahedral, hexahedral, pyramid, and wedge elements (or a combination of these) in 3D. This  flexibility allows you to pick  mesh topologies that are best suited for your particular application, as described in Choosing the Appropriate Grid Type.
You can adapt all types of meshes in FLUENT in order to resolve large gradients in the flow field, but you must always generate the initial mesh (whatever the element types used) outside of the solver, using  GAMBIT, TGrid, or one of the CAD systems for which mesh import filters exist. 

Postprocessing is the final step in CFD analysis, and involves organization and interpretation of the data and images. All Fluent software includes full postprocessing capabilities.



Kurzbeschreibung: englisch
ANSYS Maxwell is a electromagnetic field simulation software for engineers tasked with designing and analyzing 3-D and 2-D electromagnetic and electromechanical devices, including motors, actuators, transformers, sensors and coils. Maxwell uses the accurate finite element method to solve static, frequency-domain, and time-varying electromagnetic and electric fields. A key benefit of ANSYS Maxwell is its automated solution process, for which you are required to specify only geometry, material properties and the desired output. From this point, Maxwell automatically generates an appropriate, efficient and accurate mesh for solving the problem. This proven automatic adaptive meshing process removes complexity from the analysis process and allows you to benefit from a highly efficient, easy-to-use design flow.
