In order to verify the LES solution to the turbulent pipe flow problem, we will compare it against the solution obtained using standard k-e model.

Turbulent Pipe with k-e model

In the Workbench Project Page, left-click on the downward pointing arrow on the top-left corner of the TurbulentPipeLES project and select Duplicate from the drop down menu as shown in the figure below.
