Ansys Meshing – Local Sizing

#### Bookstore

Source: Ansys

The Sizing options provide greater control over the following properties:

• Mesh growth (transition) between small and large sizes based on a specified growth rate

• Curvature based refinement and angles between normals for adjacent mesh elements (curvature-based sizing)

• Number of mesh elements employed in the gaps between two geometric entities (proximity-based sizing)

By default, Use Adaptive Sizing is set to Yes, unless Physics Preference is set to CFD or Nonlinear Mechanical (in which case the default is Capture Curvature set to Yes), or Hydrodynamics (in which case the sizing is Uniform). The option you choose determines which refinement mechanisms are activated, as described in the following sections.

Controls for sizing include Element Size Growth Rate Max Size , and Curvature Min Size / Proximity Min Size . The Curvature Min Size/Proximity Min Size and Max Size specifications represent, respectively, the global minimum and global maximum allowable element size. The Element Size specification represents the global maximum allowable size of the elements created by the free surface meshers of the supported methods. The Growth Rate represents the increase in element edge length with each succeeding layer of elements from the edge or face. For example, a growth rate of 1.2 results in a 20% increase in element edge length with each succeeding layer of elements.

In this tutorial, you will learn to use Sizing tool using Ansys Meshing. With this tool you can generate a local mesh.

## Ansys Fluent Tutorial | Heatsink

In this tutorial, you will learn how to simulate a Heatsink using Ansys Fluent. In this first video, you will see how to create the geometry and the mesh using DesignModeler, Ansys Meshing and Ansys Fluent.

## Ansys Meshing | Inflation

You can set the Use Automatic Inflation control so that inflation boundaries are selected automatically depending on whether or not they are members of Named Selections groups.

You can set the Use Automatic Inflation control so that inflation boundaries are selected automatically depending on whether or not they are members of Named Selections groups.

## Ansys Meshing – Keyframe Animation

You can make animations based on keyframes. Keyframes define the start and endpoints of each section of animation.

## Ansys Meshing – Match Control

In this tutorial, you will learn how to use the Match Control tool in Ansys Meshing. Match Control allows duplicating the mesh in a body. We have two option Match Control Cyclic and Arbitrary.

## Ansys Meshing – Body of Influence

The Body of Influence option is available in the Type field if you selected a body and Use Adaptive Sizing is set to No. Using this option, you can set one body as a source of another body

## Ansys Meshing – Sphere of Influence

The Sphere of Influence option is available in the Type field after you select an entity such as a body, face, edge, or vertex.
