A complete CFD analysis consists of various phases that include pre-processing, solving equations, and post-processing.
Pre-Processing
The pre-processing stage you need to determine the equations to be solved, model the geometry and flow domain, specify the boundary conditions, and generate a computational mesh.
Determining the Equations to be Solved
To formulate the flow problem you need to seek answers to the following questions:
-
What is the objective of the analysis?
-
What is the easiest way to obtain the objective?
-
What geometry should be included?
-
What are the free-stream and/or operating conditions?
-
What dimensionality of the spatial model is required? For example, 1D, quasi-1D, 2D, axi-symmetric, or 3D.
-
What should the flow domain look like?
-
What temporal modeling is appropriate? For example, steady or unsteady.
-
What is the nature of the viscous flow? For example, in viscid, laminar, or turbulent.
-
How should the flow be modeled?
Modeling the Geometry and Flow Domain
The body about which you need to analyze the flow requires modeling. This generally involves modeling the geometry with a CAD software package. You need to perform approximations of the geometry and simplifications to...
