You can give a bias to edge sizing to cluster cells towards one end of edge. See this page for how to implement a bias to an edge.

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.

The streamlines emanating from the inlet do not include those in the recirculating region or the "deadwater" region. To see the streamlines in the recirculating region, we:

• Create points along a line within the recirculating region

• Plot streamlines emanating from these points
