Mesh

Some of the settings you can use to get a better mesh are shown in the figure below.

...

Below is a mesh we obtained by playing with these settings. This mesh resolves the separated flow behind the plaque better than the default mesh. It can be further improved though! You could start by changing the "edge sizings" in the left branch.

Streamlines

The following videos show how to plot streamlines using the CFD Post post-processor included in ANSYS Workbench. First, we plot streamlines emanating from the the inlet.

...

• Create points along a line within the recirculating region
• Plot streamlines emanating from these points

Wall Shear

The following video shows how to plot wall shear along the left wall of the bifurcating artery.

Pressure Gradient

The procedure to create a contour plot of the pressure gradient is shown in the video below.
