How to Create a CFD Mesh Using Fluent Meshing - Part 1 or 5

Fluent Meshing is ANSYS pre-processing tool of choice for Fluent users with large and complex geometries. Part 1 out of 5. A Formula One type geometry is used to demonstrate quick CAD import into Fluent Meshing. New high-resolution “surface wrapping” functionality is used to obtain a high-quality surface mesh ready for volume meshing. Such “patch independent” surface wrapping techniques are tolerant to disconnected or overlapping CAD surfaces and can be used to extract fluid regions from assemblies, avoiding the difficulties sometimes encountered using CAD-based Boolean tools. New graphical options in R15 are shown along with Diagnostic tools to find and repair problems. Fluent Meshing flexibility is shown where local nodal manipulation can be used to fix problems with the geometry at the mesh rather than CAD level.

How to Create a CFD Mesh Using Fluent Meshing - Part 2 of 5

Fluent Meshing is ANSYS pre-processing tool of choice for Fluent users with large and complex geometries. Part 2 out of 5. Our Formula One type geometry is used to demonstrate Conformal Tessellation whereby the CAD is remeshed directly at import with a pre-specified Size Field file. Such “patch conforming” surface meshing techniques are useful for cleaner CAD geometries where clean-up or fluid extraction has been done in CAD or is unnecessary. Diagnostics tools are used to assess surface mesh validity i.e. connectivity. They are also used to find and fix the few skewed faces which result from patch conforming surface meshing on thin or sharp angle patches.

How to Create a CFD Mesh Using Fluent Meshing - Part 3 or 5

Fluent Meshing is ANSYS pre-processing tool of choice for Fluent users with large and complex geometries. Part 3 out of 5. A surface mesh is used to generate a volume mesh consisting of tetrahedral and prism elements. Problems with prisms are found and the Diagnostics tools are used to show how these can be found and fixed prior to volume meshing. Fluent Meshing local geometry modification tools are again used to quickly correct these faults which otherwise would require CAD alterations.

How to Create a CFD Mesh Using Fluent Meshing - Part 4 or 5

Fluent Meshing is ANSYS pre-processing tool of choice for Fluent users with large and complex geometries. Part 4 out of 5. Here, a volume mesh from is used but we strip away the tet mesh to leave only the prism layers and re-fill the bulk volume with hexcore mesh. Enclosed fluid regions called “Domains” are used to do this and usage of some functionality is shown for manipulating volume meshes including volume mesh improvement tools.

How to Create a CFD Mesh Using Fluent Meshing - Part 5 or 5

Fluent Meshing is ANSYS pre-processing tool of choice for Fluent users with large and complex geometries. Part 5 out of 5. A conformal import of a generic F1 geometry is used here to show how we can effectively remesh surfaces using different size functions. We show how the user can compute and display size fields based upon a set of size function definitions. Filters can then be used e.g. the user can scale size fields and remesh. Remeshing is performed locally by picking triangles and surrounding rings or by picking specific boundary zones to remesh fully. The final surface mesh is fully conformal.

Webinars

How to Speed Up ANSYS 15.0 with GPUs

This webinar will present which solver options in ANSYS Fluent 15.0, including some of the typical CFD applications, can benefit from GPUs as well as the performance enhancements made to ANSYS Mechanical 15.0. Several examples will be presented to demonstrate the GPU speed ups in both CFD and FEA applications and some of the important variables that can affect performance. Recommendations on typical system configurations to maximize the productivity of both CPUs and GPUs will also be discussed.

ANSYS Inc. and NVIDIA have collaborated to bring higher simulation productivity for your CFD and FEA simulations using GPUs in ANSYS 15.0. In addition, a new license scheme will be in effect that treats each GPU socket the same as a CPU core in all HPC license products. As a result, you can now do more simulations than before without missing project deadlines by simply adding GPUs to your existing HPC infrastructure.

Technical Brief

SVD-ROM for Battery Thermal Management

Battery thermal management for high-power applications such as electric vehicles (EVs) and hybrid electrical vehicles (HEVs) is crucial to prevent thermal runaway. This application brief describes a reduced-order model (ROM), called SVD-ROM, based on singular value decomposition (SVD). This ROM provides results very similar to those from computational fl uid dynamics (CFD) under any transient power dissipation. The ROM runs orders of magnitude faster than the original CFD model.

ANSYS SIwave-DC

ANSYS SIwave-DC™ analyzes entire printed circuit boards (PCBs) and integrated circuit (IC) packages prevalent in modern electronic products. SIwave-DC accurately predicts failure risks within a design, such as DC voltage drop and power loss per layer, along with DC resistance of power planes, ground planes and signal traces. These capabilities make it an eff ective tool to perform pre-layout power distribution network analysis and reduce post-layout power delivery problems.

Preprocessing Best Practices about SpaceClaim versus ANSYS DesignModeler

Time to solution in a simulation process is a matter of a sensible and efficient choice of pre-processing tools (CAD handling and meshing), which is still the main consuming part in most cases.

These two are closely linked (through the type of cell used, CAD complexity, etc.) to define the best way to generate a mesh from a given geometry. ANSYS has in its portfolio a set of tools in each of these areas that will allow you to mesh and run with success any type of applications.

This webinar will mainly focus on the first step of this process - CAD handling with the use of either ANSYS DesignModeler or SpaceClaim. The webinar will begin with a brief summary of the scope of capabilities for each of these tools, but also their strengths and weaknesses, followed by a set of constrains that partially define and lead your choice.

Also in this webinar some Bests and Practices will be presented based on industrial cases to better illustrate the previous comments.
