Use the Interior Temperature Variation condition to model a thermal type of source on an interior boundaries,
Tt =
Tbnd. This can, for example, be a thin sheet that has a harmonically varying temperature, given by
Tbnd, for example, due to ohmic heating. This temperature fluctuation will give rise to acoustic waves that can be modeled using the Thermoviscous Acoustics interface and this boundary condition.
Select a Mechanical condition —
No slip (the default) or
Slip. See the
No Slip and
Slip conditions for further details.
Enter a value or expression for the Temperature variation Tbnd (SI unit: K) that has to be applied at the interior boundary.
