What is CFD?
• CFD = Computational Fluid Dynamics
– Computer models that predict how fluids behave
– Uses mathematical models to describe aspects of
fluid behaviour
– Use commercial CFD software from ANSYS
– Based on the finite volume approach

CFD – Step 1
Geometry Creation
• Create from 2D
drawings
•
Import from a range
of CAD packages
– Parasolid
– IGES
– STEP
– ACIS
CFD – Step 2
• Develop mesh
• Define boundary
conditions
CFD - Step 3
• Setup boundary
conditions
• Initialise solution
CFD – Step 4
• Iterate to
convergence
– Steady state
problems
– Transient problems
CFD – Step 5
• Post-Process
Results
• Quantify
– Mass flux
– Velocities
– Pressures
– Forces
– Lift/Drag
– Free surface
