CFD 2D Mesh

Use the CFD 2D Mesh tool to generate hybrid grids containing hexa/penta/tetra elements in the boundary layer and tetra elements in the core or fare field.

  1. From the Mesh ribbon, 2D Mesh tools, click the arrow on the right of the selected surface mesh tool to view a drop-down list of available mesh methods. Select CFD 2D Mesh from this list.

  2. Optional: On the guide bar, click to define surface mesh options.
  3. Select surfaces to mesh.
    You can also select solids by changing the target from the guide bar drop-down menu.
  4. Click Mesh on the guide bar.

Tip: On the guide bar, click to open the Advanced Selection dialog, from which you can filter geometry further by selecting a subset of entities based on additional selection methods, such as By Component or By Assembly.

CFD 2D Mesh Options

Element size
Set the average element size.
Element type
Select the type of elements used to create the mesh.
Curvature based refinement
Option to turn on mesh refinement based on geometric curvature.
Method
Select the adaptive meshing method.
Minimum size factor
The minimum element size, as a factor of the average element size. Value must be less than or equal to 1.
Maximum deviation factor
The maximum allowable deviation between an element edge and a geometry edge, as a factor of the average element size.
Feature angle
The maximum allowable break angle between adjacent elements.
Growth rate
The factor to control the rate of transition in case of element size change.
