Visualizing and Initializing the Solution

We will view the air and water distributions throughout the run and also save this plot at regular intervals in order to create an animation.

Right-click on the Scenes node and then select New Scene > Scalar.

In the object tree, select the new Scenes > Scalar Scene 1 > Displayers > Scalar 1 > Scalar Field node.

In the Properties window, change the Function property setting to Volume Fraction of H2O.

Select the Scalar 1 node and change the Contour Style property setting to Smooth Filled.

Select the Attributes > Update node.

Check the Output Frame To File box and specify the File Path, Offscreen Width and Offscreen Height properties as desired.

Make the Scalar Scene 1 display active to look at the initialization result.

As expected, at the start of the run the left chamber is entirely filled with water whereas the right chamber and the connecting channel are entirely filled with air. A small region in which both fluids are apparently present is visible at the interface between the two fluids, but this effect is simply due to the coarseness of the mesh.
