KNOWN ISSUE: Error in moving mesh correction for pressure-work term at Domain Interfaces (Class 3 Error)

In moving mesh cases that also use the Total Energy model, unphysical temperatures and/or fluctuations in temperature may be present in the solution at or near Domain Interfaces.

For cases that involve mesh deformation, an additional contribution to the pressure-work term in the Total Energy equation is required at Wall and Domain Interface boundaries. This contribution was incorrectly omitted for Domain Interfaces.

For relatively low speed flows, it may be possibe to use the Thermal Energy equation without adverse effects. However, the solution should be checked carefully.
