Validate each physical component separately before coupling multiple solvers. Check units and interface conditions carefully, then vary mesh and timestep settings to assess numerical sensitivity. Keep the solver configuration and material references with the project, and inspect conservation or balance quantities rather than evaluating success solely through a plausible-looking visualization.
This is best suited to researchers studying coupled physical phenomena. Before committing a larger project, account for these trade-offs: coupled models can be difficult to configure; some installations require building components.
