Calculators

Estimate first cell height for CFD near-wall mesh setup from target y+, flow conditions, and wall-treatment assumptions.

Calculate flow regime and turbulence onset using SI inputs for engineering flow-regime estimates.

Calculate Courant number from SI inputs (velocity, time step, cell size) for CFD stability estimates.

Estimate turbulence intensity, length scale, turbulent kinetic energy, and dissipation-related inlet quantities for CFD boundary condition setup.

Calculate the Grid Convergence Index for CFD mesh refinement studies and estimate numerical uncertainty using three-grid solution data.

Estimate laminar and turbulent boundary layer thicknesses over a flat plate for CFD mesh sizing.

Estimate an extrapolated grid-independent value from three CFD mesh-refinement results and review apparent convergence behavior for numerical verification.

Calculate equivalent mesh refinement ratios from CFD cell counts or representative mesh sizes for Grid Convergence Index and Richardson extrapolation studies.

Calculate total inflation-layer thickness, last-layer height, and target boundary layer coverage for near-wall CFD meshes.
