FLUENT - Flat Plate Boundary Layer Step 4

Useful Information

Click here for the FLUENT 6.3.26 version.

Step 4: Setup (Physics)

Analyze Mesh

First, we check the Mesh to make sure that there are no errors.

Problem Setup > General > Mesh > Check

Any errors in the Mesh would be reported at this time. Check the output and make sure that there are no errors reported.

Main Menu > Mesh > Info > Size

How many cells and nodes does the Mesh have? You can check this in the graphics window where the mesh should be displayed. If it is not, you can display the mesh by going to

Problem Setup > General > Mesh > Display

Define Governing Equations

Problem Setup > Models > Energy

Use the default and click OK.

Problem Setup > Models > Viscous

Select Laminar under Model and click Edit.


 
We want to leave the default value so you can click Cancel.

Problem Setup > Materials

Double click air or select it and click Create/Edit. Make sure air is selected under Fluid Materials. Set Density to 1.00 and Viscosity to 1e-4 so that we can get Re of 1e4.

Define Boundary conditions

Problem Setup > Boundary Conditions

Set the inlet boundary type to velocity-inlet. Then click Set...Set the velocity magnitude to 1 m/s. Set the outlet type to pressure-outlet boundary. Use gauge pressure of 0 Pa.Use the default value of wall for the plate. Set the far field to symmetry boundary type. Symmetry boundary condition means that the component normal to the wall is zero.

Problem Setup > Boundary Conditions

 > Operating Conditions


 
Use the default value. Click OK.
