Use the Interior Impedance node to apply a transfer impedance condition on an interior boundary. Add this node from the
Interior Conditions submenu.
Select a condition for the Tangential velocity —
Slip (the default) or
No slip. The
No Slip option will apply an additional constraint for the velocity in the tangential direction on the two sides of the interior boundary.
Select a Thermal condition —
Isothermal (the default) or
Adiabatic. See the
Isothermal and
Adiabatic conditions for further details.
