Generating the Mesh
Generate a mesh of tetrahedral elements for the manifold. To improve accuracy of the solution, add mid-side nodes to the tet4 elements to generate quadratic tet10 elements.
- Right-click the node and select .
-
In the
Create Automated Mesh Operation dialog:
- Rename the Stress Analysis - Tetrahedral Mesh. node to

Edit the
node and set the following properties:
Node Property Setting Base Size Value 0.005 m Minimum Surface Size Percentage of Base 30 - Right-click the Stress Analysis - Tetrahedral Mesh node and select Execute.
By default, mesh operations generate a mesh of linear elements. To add mid-side nodes to the linear tet4 elements:
- Select the Add - Linear Interpolation. node and set Mid-side Vertex to
Simcenter STAR-CCM+ adds the mid-side nodes during the solution initialization. In this tutorial, you want to add the mid-side nodes before you run the simulation, so that the mid-side nodes are available on the FE mesh when you map the thermal loads to the mesh vertices. Initialize the solution to generate the mid-side nodes:
-
Click
(Initialize Solution).
To visualize the volume mesh and element type:
- Create a scalar scene and rename it to Manifold Mesh (FE).

The number 24 identifies tetrahedral elements with mid-side nodes.
