Initial Conditions
In this tab simple initial conditions can be set. In this case, initial values for all the relevant
quantities will be set to 0 except the velocity component in the x-direction.

• Select the Initial Conditions tab on the left-hand side of the TransAT user interface
• Click U-Velocity in the quantity tree

• Set Method to Constant and Value to 0.005
• Proceed as above to set the initial state of the remaining quantities as follows

V−Velocity
Method : Constant
Value : 0
W−Velocity
Method : Constant
Value : 0

Pressure
Method : Constant
Value : 0

Output Management Tab
In this tab the parameters of the outputs of the simulation are defined.

• Click Output Management on the left-hand side of the TransATUI

• Set the Output File Format and Frequency of output files from Iteration / timestep
number as follows

Output F i l e Format : Paraview
Frequency of output f i l e s : Time I n t e r v a l − 4 s

• Click to select the variables for which data is to be saved

• Activate the following variables in the Output Variables window then click to save the
settings and close the window

Primary v a r i a b l e s :
Pressure : ON
U−Velocity : ON
V−Velocity : ON
W−Velocity : ON
P a r t i c l e Tracking :
P a r t i c l e Volume Fraction : ON
