Setting Initial Conditions

In compressible fluid problems it is generally advisable to initialize the flow to a non-zero initial velocity and a meaningful pressure. Here, we use the free-stream velocity and the duct outlet pressure.

Select the Physics 1 > Initial Conditions > Velocity > Constant node.

Set the Value to 72,0,0.

In the same Initial Conditions node, select the Static Pressure > Constant node.

Set the Value to -7903.35.

Save the simulation.
