HM-3270: Use the Tetramesh Process Manager
The Process Manager contains a step-by-step checklist of procedures that allow you to quickly organize and tetramesh a geometric model. Each step is formatted in a hierarchical list that provides the order in which the process must be performed. Specialized tools are also provided at each step to simplify the process. You can perform these steps manually, but it is generally faster to perform them in the Tetramesh Process Manager.
- Import geometry or a HyperMesh file
- Clean up geometry
- Organize the model (holes and features)
- Establish mesh size and pattern for the organized geometry
- Create a 2D mesh
- Clean up the 2D mesh
- Create a 3D TetraMesh
This exercise uses the tetmesh_pm.hm file, which can be found in the hm.zip file. Copy the file from this directory to your working directory.
Initiate the Process Manager
In this step you will initiate the process manager.
Import Geometry
In this step you will import geometry.
At this point, the TetraMesh Process Manger automatically assembles the TetraMesh process flow. The first step, Geometry Import, is highlighted in the tab area, and the panel area has been configured with specific panels for aiding the TetraMesh Process Manager template.
If you need to access standard HyperMesh panels, undock the Process Manager panels to a separate dialog by clicking in the panel area. To re-dock the Process Manager panels, click in the Process Manager dialog.
Clean Up the Geometry
In this step you will clean up the geometry.
Organize and Clean Up Holes
In the Organize and Cleanup Holes step, you will organize the surfaces that form holes in the model.
The TetraMesh Process Manager can automatically sort and organize holes into separate component collectors based upon their diameter. This will allow you to specify a mesh type, circumference element count, and longitudinal element size for different hole groups.
Mesh Holes
In this step you will mesh holes.
Organize Features
In this step you will organize and clean up features.
In the Organize and Cleanup Features step, you will highlight and organize features that require specific mesh controls beyond the overall mesh pattern that will be applied to the remainder of the part in a later step. You will use the organizational tool to place the required surfaces into their own collector or collectors, and set a mesh size and pattern requirements for each.
Organize Fillets
In this step you will organize and clean up fillets.
Often a better mesh can be achieved if your fillets are split down the center. In the Organize and Cleanup Fillets step, you will split your fillets based on a minimum and maximum radius criteria.
Mesh Features
In this step you will mesh features.
In the Mesh Features step, you will mesh the features that you organized in step 6. The panel area will contain a table with your organized features. In the table, you will be able to select a mesh type and specify an element size for each feature.
Organize and Clean Up
In this step you will organize and clean up the remaining portion of the model.
As the remaining surfaces are already in the component you wish them to be in, there is no need for further organization.
Mesh and Remesh
In this step you will globally mesh the remaining model.
You can select a mesh type and specify an element size for all components that remain unmeshed.
- In the panel area, type 1 in the Element Size field.
- Set Mesh Type to trias.
- Click Mesh.
- Click ACCEPT.
Clean Up Elements
In this step you will clean up elements.
At this point the model should be entirely surface meshed. Proper adherence to the previous steps ensures a surface mesh that is properly connected and controlled by the previously entered values. In the Element Cleanup step, you will verify a proper mesh and clean up any issues that are found.
Tetra Mesh Model
In this step you will tetra mesh the model.
Tetra Meshing is the final step in the TetraMesh Process Manager Template. During this step, the model will be Tetra meshed. The Process Manager automatically opens the TetraMesh panel and pre-selects all of the float and fixed elements.
Save Your Work
In this optional step you will save your work.
