How to create a thermal coupling between 2D and 0D elements?

Details

To create a thermal coupling between 2D elements and 0D elements using a heat transfer coefficient, use the following guidelines:

• Select a 0D element as the secondary region.
• Use a One-to-One coupling resolution. This calculates a single conductance from each primary element to the nearest secondary element. Primary elements are not subdivided.
• Clear the Only Connect Overlapping Elements option. When you disable this option, the solver connects elements based only on the distance between elements. It connects each primary sub-element to the closest secondary element, in this case to the 0D element.
• Clear the Elements Part of a Thermal Coupling Do Not Convect to Environment option in the Solver Parameters dialog box, on the Thermal Solver page, in the Thermal Coupling group, if you want all selected elements to participate in the convective exchange with the environment. If this option is selected, the thermal solver identifies whether the top or bottom side of the elements is part of the thermal coupling and excludes it from convection to the environment. Depending on the position of the 0D element, certain 2D elements with the top side in the thermal coupling may be excluded from the convection to the environment condition.
