Tutorial: Tet-Dominant algorithm – Pipe-flow meshing tutorial
This meshing tutorial demonstrates how the Tet-Dominant meshing algorithm can be used to generate high-quality meshes for internal flows.

- As a first step we need to create a new simulation. To create a simulation left click on the pipe and then on Create Simulation.
Boundary layer Refinement
- In order to correctly model the flow through a pipe the boundary layer has to be resolved accurately. This can be achieved by refining the mesh in the regions close to the walls.
- The best method to do this is by the help of a layer inflation mesh refinement. To add a mesh refinement, click on ‘+’ icon next to refinements under the mesh.
- Select the layer Inflation setting
- In the mesh refinements settings, change the type from local element size to layer inflation.
- Change the total layer thickness to 0.01 m and leave the rest of the settings as the default values.
- The next step is to pick the faces.
Mesh Inspection and Mesh Clip Generation
- Once the mesh is generated, we can check the event log for further information on our mesh.
- The mesh has 380.5k cells and 120.1k nodes.
- The Boundary layer generated can easily be seen by zooming on the mesh inlet. We see 5 layers on the boundary layer with increasing thickness.
- Click on generate mesh clip to inspect the internal mesh. Adjust the settings of the normal. Click on generate mesh clip icon.
- The mesh clip generated is presented below
