Features
Practical CFD capabilities in a coherent graphical interface
EasyCFD brings geometry, meshing, calculation and result analysis together.
Pre-processing
Prepare the numerical problem
- Draw geometry directly in the application
- Import geometry from DXF or point-data files
- Generate structured and unstructured meshes
- Specify physical properties and boundary conditions
- Choose first- or second-order upwind and TVD convection schemes
Physics and solution
Model flow and heat transfer
- Two-dimensional and axisymmetric domains
- Laminar and turbulent flow
- Standard, RNG and Realizable k-ε models
- SST k-ω and Spalart–Allmaras models
- Transition k–kL–ω model
- Steady-state and transient calculations
- Conduction, convection and conjugate heat transfer

Post-processing
Turn numerical results into engineering insight
Velocity vectors
Inspect local flow direction and magnitude across the domain.
Contours
Create colour-shaded and line-contour representations.
Data extraction
Generate XY plots and domain or boundary statistics.
Numerical methods
Control accuracy and robustness
Select the spatial and temporal discretization appropriate to each stage of the calculation.
Upwind schemes
Use first-order upwind for robustness or second-order upwind for increased spatial accuracy.
TVD schemes
Apply bounded high-resolution TVD schemes with a choice of flux limiters.
Transient accuracy
Select first- or second-order time discretization for unsteady simulations.
Solver control
Set relaxation, convergence criteria and residual monitoring for the coupled equations.
