Limitations

Simulations are only as good as the input data and assumptions. Real-world conditions may introduce variables not captured in the model.

Reliability & validity

The validity of the CFD simulation relies on the accuracy of the Navier-Stokes solver and the input parameters. Reliability would be assessed by repeating the simulations with slight variations in parameters or by comparing results to experimental data if available.

Think critically
