Mesh

In this section the geometry will be meshed using inflation feature to cluster more cells near the wall of the cylinder.

Launch Mesher

In order to begin the meshing process, go to the Workbench Project Page, then (Double Click) Mesh.

Inflation Feature (Mesh Control).

Right-click on the Mesh, in the Outline view, choose Insert and then choose Inflation.

...

From the Mesh Statistics (in the figure above) we observe that we have about 0.85 million elements which would require multiple cores to run the simulation.

Create Named Selections

Here, the faces of the geometry will be given names so one can assign boundary conditions in Fluent in later steps. The left face of the pipe will be called "Inlet" and the right face will be called "Outlet". The lateral (or curved) surface of the pipe will be called "PipeWall".

...

Repeat the same procedure for the other two faces.

Save, Exit & Update

First save the project. Next, close the Mesher window. Then, go to the Workbench Project Page and click the Update Project button,  .

Go to Step 4 - : Physics Setup (Physics)

Go to all FLUENT Learning Modules
