TransAT Tutorial Manual 1.3. Flow over a Cylinder (Re=20)

• Set the parameters of the window as follows
Basic Equations :
Pressure : ON
U Velocity : ON
V Velocity : ON
W Velocity : OFF
Temperature : OFF
Concentration : OFF

• Activate Reference Properties and click to the right.

• Set the following parameters in the reference properties window then click to save the
settings
Reference Pressure : 0
Reference Velocity : 0.002
Reference Length : 1.0

Phase Properties
The Phase Properties tab is used to define the phases of the flow. Since the Multiphase
Flow Method is turned off, only the fluid properties of Phase 1 need be defined. A custom phase
can defined by directly entering the values for its properties.

• Click Phase Properties on the left-hand side of the TransATUI

• Select Phase 1 in the phase tree and enter the following values of the physical properties
Phase 1
Density : 1.0
Viscosity : 0.0001 ( constant )

Simulation Parameters
This tab is used to define the numerical properties of the simulation.

• Click Simulation Parameters on the left-hand side of the TransATUI

Simulation Type and Control Parameters

• Set the following parameters to solve for a steady flow.
