Define No Slip Walls
Use the No Slip tool to define physical walls in the simulation domain.
No-slip specifies the velocity of the fluid at the surface of the wall. For example, for a stationary wall in viscous flow, a wall boundary condition would change all the components of the velocity to zero.
-
Select the surfaces or thin solids on which
to apply the boundary condition.
To Select Do This Surfaces Select surfaces in the following ways: - While in the Flow ribbon, select surfaces, then right-click and select from the context menu.
- From the Flow ribbon, click the
No Slip
tool.
Select surfaces.
Thin Solids - From the Flow ribbon, click the No Slip tool.
- Change the guide bar selector to Thin Solids.
- Select thin solids.Note: You can only select thin solids if layers have been defined using the Thin tool.
- Select a direction option from the
guide bar.
- Direction: Away from Parent Surface - Define the condition on the boundary surface furthest from the parent surface.
- Direction: Adjacent to Parent Surface - Define the condition on the boundary surface closest to the parent surface.
- Direction: Both Sides - Define the condition on both sides of the boundary surface.

From the guide bar, execute the command in the following
ways:
- Click to confirm your selection and remain
in the tool.
This allows you to continue creating instances and helps you visualize and edit instances with the legend.
- Click to confirm your selection and exit the tool.
