Bias Type and Bias Option

For edges only, use Bias Type to adjust the spacing ratio of nodes on an edge. This feature is useful for any engineering problem where nodes need to be clustered on an edge or group of edges, or if there is a need to bias the mapped mesh of a face towards a specific direction with respect to the edges of the face. Bias Type can be used with all meshers except the Patch Independent Tetrahedron method and the assembly meshing algorithms. To use Bias Type, choose one of the four pre-determined patterned options depicted pictorially from the Bias Type drop-down menu:

 

Note:  The MultiZone meshing method respects all Bias Type options. The nodes generally follow the distribution. However, some optimization can be done to improve transition with other mesh, or to improve the quality. Setting the Behavior to Hard will give higher priority to the bias settings defined than the optimization.

In this tutorial, you will learn how the BIAS FACTOR tool works in Ansys Meshing. You can download the Excel file from the following link.

Ansys Meshing – Mesh Copy Control

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.

The Pinch feature lets you remove small features (such as short edges and narrow regions) at the mesh level in order to generate better quality elements around those features.

When geometries are complex or the range of length scales of the flow is large, a triangular/tetrahedral mesh can be created with far fewer cells than the equivalent mesh consisting of quadrilateral/hexahedral elements.
