Initial Conditions
In this tab simple initial conditions can be set. In this case, the velocity components and the
temperature are initialised to the same values as the ones prescribed at the inflow over the whole
domain. Pressure is initialised to 0 Pa over the domain.

• 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 0.01

• Proceed as above to set the initial state of the remaining quantities as follows
