Reproduce a tutorial close to the intended flow regime before changing geometry or physics. Check mesh quality, boundary conditions, and conservation behavior, then compare results across mesh or timestep refinements. Keep case files and solver versions together, and validate important predictions against accepted benchmarks or measurements rather than relying only on visual flow fields.
This is best suited to engineers conducting computational fluid dynamics studies. Before committing a larger project, account for these trade-offs: requires CFD and numerical-method knowledge; reliable results need mesh and model validation.
