Fluent automatically decomposes your computational area into smaller subdomains as the number of nodes increases to disperse the computational strain. Inefficient communication between nodes might produce instability or divergence if the domain decomposition is not appropriate.
Troubleshooting problems with parallel CFD simulations may be difficult, and it frequently entails a mix of modifying simulation parameters, optimising domain decomposition, and taking hardware limits into account. When growing the number of nodes, it is critical to methodically test alternative configurations and monitor performance to determine the underlying cause of divergence and failures.
