CFD help is one-to-one support from a simulation engineer who explains how fluid flow is solved numerically and helps you set up, run and validate simulations. For flow theory itself, see fluid mechanics help.

This map lists the core computational fluid dynamics (cfd) topics, the point where students most often get stuck, and how a tutor helps you past it.
| Topic | Where students get stuck | How a tutor helps |
|---|---|---|
| Governing equations | Continuity, momentum and energy | Equation summaries |
| Discretisation | Finite difference and finite volume | Worked discretisation examples |

Tutors cover CFD theory and practice.
| Area | Topics |
|---|---|

| Numerical methods | Finite difference, finite volume, pressure–velocity coupling (SIMPLE) |
| Meshing | Grid types, quality metrics, y+ and near-wall treatment |

Two set-up checks.
| Question | Working | Answer |
|---|---|---|
| Velocity 2 m/s, cell size 0.01 m, time step 0.004 s. Courant number? | CFL = uΔt ÷ Δx = 2 × 0.004 ÷ 0.01 | 0.8 |
| Largest time step for CFL = 1 | Δx ÷ u = 0.01 ÷ 2 | 0.005 s |
| Water at 1 m/s in a 0.1 m pipe (ν = 1 × 10⁻⁶ m²/s). Reynolds number? | uD ÷ ν | 100,000: turbulent, so use a turbulence model |
Explicit schemes usually need CFL below about 1 for stability; implicit schemes allow larger time steps but accuracy still matters.
A drag coefficient is computed on three meshes, each refined by a factor of 2: coarse 1.120, medium 1.105, fine 1.100.
| Step | Working | Result |
|---|---|---|
| Observed order of accuracy | p = ln[(1.120 − 1.105) ÷ (1.105 − 1.100)] ÷ ln 2 = ln 3 ÷ ln 2 | ≈ 1.58 |
| Extrapolated value | 1.100 + (1.100 − 1.105) ÷ (2^1.58 − 1) | ≈ 1.0975 |
| Change from medium to fine mesh | (1.105 − 1.100) ÷ 1.100 | ≈ 0.45% |
Report the mesh study alongside validation against experiments or published data.

Most lost marks come from results presented without verification.
| Mark-loser | What to do instead |
|---|---|
| No mesh independence study | Run at least three meshes and compare |
| Residuals as the only convergence check | Monitor key quantities such as drag or pressure drop |
| Wrong boundary conditions | Match conditions to the physical problem |
| Turbulence model chosen without reason | Justify the model for your flow |
| Poor near-wall mesh | Check y+ for the wall treatment used |
| Pretty contours without numbers | Report quantitative results and compare with data |
Computational fluid dynamics (CFD) is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Simulation projects | Well-set-up, verified and validated cases |
| Reports | Method, mesh study, results and discussion |
| Coding tasks | Simple finite difference or finite volume solvers |
| Exams | Theory, schemes and stability |
| Presentations | Clear explanation of results |
CFD engineers use these tools.
| Tool | What it is used for |
|---|---|
| ANSYS Fluent | General-purpose CFD |
| OpenFOAM | Open-source CFD |
| STAR-CCM+ | Industrial CFD |
| ParaView | Post-processing |
| Python or MATLAB | Writing simple solvers |
Computational fluid dynamics (CFD) is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where computational fluid dynamics (cfd) is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | MEng and MSc mechanical, aerospace and chemical engineering | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | CFD courses in mechanical and aerospace programmes | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Mechanical and aerospace engineering degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Engineering programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | B.Tech/BE and M.Tech mechanical, aerospace and chemical CFD courses | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of computational fluid dynamics (cfd) help depends on the case complexity and your deadline. A short set-up check costs less than a full simulation project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Yes. Tutors help set up, run and validate simulations, within your university's rules.
Using numerical methods to solve fluid flow equations on a computer.
The conservation equations for mass, momentum and energy, often the Navier–Stokes equations.
A method that integrates conservation equations over small control volumes, conserving fluxes.
Courant–Friedrichs–Lewy number, uΔt ÷ Δx, which affects stability of time-stepping schemes.
When refining the mesh no longer changes key results significantly.

It depends on the flow; k-ω SST is common for many external and internal flows.
A pressure–velocity coupling method used to solve incompressible flow equations.
Common causes are poor mesh quality, bad boundary conditions, high time steps or unsuitable schemes.
Verification checks that equations are solved correctly; validation checks that the model matches reality.
