CutCell meshing is a general purpose hex-dominant meshing technique. The CutCell meshing algorithm is suitable for a large range of applications, and due to the large fraction of hex cells in the mesh, often produces better results than regular tetrahedral meshes. This method can be used instead of tetrahedral or hexcore meshing, without requiring a very high quality surface mesh as a starting point. Also, this method uses a direct surface and volume approach without the need of cleanup or decomposition, thereby reducing the turnaround time required for meshing.
The CutCell meshing process involves the following approach:
- Objects, material points (optional), and size functions are defined.
- The initial size of the Cartesian grid is computed based on the minimum and maximum size set for the size functions.
- A uniform Cartesian grid is created within the bounding box for the geometry.
The base size for the Cartesian grid is computed from the minimum and maximum size specified in the Size Functions dialog box as follows:
Base Size = 2n × Min Size
Base Size ≤ Max Size
where n is the number of refinement levels.
In this tutorial, you will learn to use the CutCell tool using Ansys Meshing. This mesh is enabled in Ansys Fluent and allows to refine it in a structured way.
You can make animations based on keyframes. Keyframes define the start and endpoints of each section of animation.
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.
Refinement controls specify the maximum number of times you want an initial mesh to be refined.
By default, the application uses the Automatic Method control, which attempts to use sweeping for solid models and quadrilateral element generation for surface body models.
Available when Use Adaptive Sizing is set to Yes, the Resolution option controls the mesh distribution. The default setting is Program Controlled.
For solid models, meshing technologies from ANSYS provide robust, well-shaped quadratic tetrahedral meshing on even the most complicated geometries.
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.
The Mesh Copy control enables you copy mesh from one body to another. This option can be used to reduce the mesh setup time for repetitive bodies/parts. Association to CAD is maintained after performing mesh copy.
Mesh controls are scoped only to the source anchor body. When the mesh is generated, the source anchor body is meshed and the mesh is then copied to targets.
