Depending on the type of coupled analysis being performed, additional physics setup steps may be necessary. When applicable, consider:
- Compatible material properties:
When using the same material(s) in multiple participants, take care to ensure that material common properties (for example, conductivity) are consistently defined. This consideration is often relevant in analyses involving thermal data transfers and, in particular, should always be taken into account for thermal analyses involving an electromagnetic participant.
For example, if Heat Rate and Temperature values are to be transferred between an electromagnetic solver and a thermal solver, both models must be made of materials that allow for temperature-dependent properties (for example, electrical conductivity and thermal conductivity, respectively).
- Identify same interface sides:
For coupled analyses that include thin bodies — such as plates, baffles, airfoils, or thin fluid gaps — ensure that System Coupling can find the correct interface sides. This process is automated but can be customized, as described for the FaceAlignment setting in the System Coupling Settings and Commands Reference documentation.
- Compatible topological properties:
For coupled analyses that will include data transfers between regions of different topologies, ensure that the models have compatible circumferential extents and geometric alignment. For more information, see Defining Geometry Transformations for Models with Different Orientations.
- Appropriate motion definitions:
Stationary bodies: Ensure that stationary bodies will not move from the reference position or participate in multiple reference frames during the co-simulation.
Moving/rotating bodies:
Ensure that motion/rotation is defined for all bodies that will move or rotate during the co-simulation.
When motion is defined on a coupled region, ensure that the motion is defined consistently for both coupling participants. (Currently, this is supported only for electromagnetic-thermal analyses between Maxwell and Fluent coupling participants.)
Tip: When motion is defined on coupled bodies, Ansys recommends that you monitor the System Coupling Transcript's Mapping Summary sections during execution to ensure that the bodies move consistently throughout the analysis.
