The coupling of flow, temperature and structural analysis is another way of virtually representing the complexity of physics. This refers to all the constellations in which at least one of the three disciplines is directly influenced by the other two. It is most likely that the temperature field interacts with both the flow and the structure.
The same considerations apply for the realization of such a multiphysics simulation as for the coupling of the individual fields:
- Temperature and structure analysis
- Fluid flow and structural analysis
- Fluid flow and temperature analysis
However, the further increase in model complexity often means that an integrated solution no longer makes sense, at least if the model descriptions for all disciplines are three-dimensional. The compromises and restrictions would be too great. Depending on the objectives and strength of the interaction, different approaches for solving the multidisciplinary task arise. It is at the responsibility of the calculation engineer to find a suitable strategy for the task at hand.
