Introduction

  • This example uses the stl file of a Cantilever Beam to generate a mesh around the cantilever.

Geometry

Use given cantileverBeam.stl file as geometry.

Click the [Import] button at the bottom to select the stl file.



Create computational domain

Click the [Add] button and select [Hex6] and set values as follows

  • Name : Hex6_1
  • Type : None
  • MIn. : (-0.4 0 0)
  • Max. : (1.2 0.2 0.5)


Create hexahedron for refinement

Click the [Add] button and select [Hex] and set values as follows

  • Name : Hex
  • Type : None
  • MIn. : (-0.05 0 0)
  • Max. : (0.2 0.04 0.2)


In Geometry, select Hex_1_surface and right-click and select Edit/View. In the window that opens, change the type as [None].


Click the [Next] button to move on to the next step.

Region

Click the (+) icon at the top to create a region. Move the mouse to the intersection of the lines that appear in light green color in the graphics window and position it inside the computation domain. Click the [Add] button to complete the setup.


Click the [Next] button to move on to the next step.

Base Grid

Select [Use Hex6] option and set the number of grids to 100, 12, and 30. Click the [Generate] button to generate the base grid.


Click the [Next] button to move on to the next step.

Castellation

Surface/Feature Refinement

Click the (+) icon under [Surface/Feature Refinement] and set the following settings

  • Surface Refinement
    • Minimum Level : 3
    • Maximum Level : 3
  • Feature Edge refinement Level : 3
  • Surfaces : cantileverBeam_surface_0


Volume Refinement

Click the (+) icon under [Volume Refinement] and set the following settings

  • Volume Refinement Level : 2
  • Volume : Hex_1

Click the [Refine] button and the castellation step starts.

Click the [Next] button to move on to the next step.

Snap

Use the default settings and click the [Snap] button to start snap.

Click the [Next] button to move on to the next step.

Boundary Layer

Click the (+) icon under [Configuration] to add a [Setting], and set it as follows

  • Number of Layers : 5
  • Thickness Model Specification : First and Expansion
  • Size Specification : Relative
  • First Layer Thickness : 0.1
  • Expansion Ratio : 1.2
  • Min. Total Thickness : 0.01
  • Boundary : cantileverBeam

Use default values for [Advanced] Configuration.

Click [Apply] button to start boundary layer step.

The final mesh looks like this



Click the [Next] button to move on to the next step.

Export

Click [Export as BaramFlow project] to export the mesh to the desired location.
