Modeling ducts with 1D elements and their walls with 2D elements

• Use a Duct, Duct with Mass Flow, Duct Axisymmetric, or Duct with Mass Flow Axisymmetric type of 1D duct mesh collector.

• Mesh the wall using 2D elements and couple them to the 1D elements using a Thermal — Coupling Convection simulation object.
