Contours
The most common contours are velocity magnitude, total pressure coefficient and pressure contours across the domain. The steps to create contours are:
- Click Load Results in the Simulation Panel.
- Select the required result file in the ensuing Load Results dialog box, click Open.
Create a section
A section is created with the following steps.
- Click Create a Cross-Section
icon in the Geometric Entities Panel. A new section Section 01 is created under Derived Surfaces.
- Select the Section 01 under Derived Surfaces and specify the Type and Position as Plane Y and 0 m in the Geometry Tab of Properties Panel.
Velocity Magnitude
- Select Section 01 under Derived Variables in the Geometric Entities Panel.
-
Select Velocity Magnitude under Derived Variables list for the Variable drop-down list in the Results Panel.

Total pressure coefficient
- Select Section 01 under Derived Variables in the Geometric Entities Panel.
-
Select Total Pressure Coefficient under Derived Variables list for the Variable drop-down list in the Results Panel.

Iso surfaces contours for wake regions
- Click Create an Isosurface
icon in the Geometric Entities Panel. An Isosurface 01 is created under Derived Surfaces.
- Select Isosurface 01 under Derived Surfaces.
- Select Velocity X [Flow] from the Variables list in the Isosurface Variable drop-down list in the Geometry Tab of Properties Panel.
- Select Below Value from the Option drop-down list.
- Enter 0 m/s for Value.
