Plots

This section shows some of the common plots used in the VOF-tank filling simulation. The steps to create the plots are:

1. Click Load Results in the Simulation Panel.
2. Select the required result file in the ensuing Load Results dialog box, click Open.

Volume Fraction

The volume fraction is monitored with the volume fraction plots.

1. Select Tank under Volumes in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in the Plot Panel toolbar, select Volume Fraction under Component air.
4. Click Plot Selected Variables icon.
5. Select Volume Fraction under Component fuel, click Plot Selected Variables icon.

 

Note: The above plot shows Volume Fraction of gas and oil in the tank. As the time of filling increases oil in the tank is incressing up to 81%. Air in the tank is exhausted through the vent out and decreasing up to 19%.

Pressure

The tank pressure is monitored at the monitoring point Tank_pressure point. It is obtained as follows:

1. Select Tank_pressure point under Points in the Geometric Entities Panel.
2. Click Add XY-Plot icon in the Toolbar.
3. Click Click for Variable List icon in Plot Panel toolbar, select Pressure in the Flow list.
4. Click Plot Selected Variables icon in the Plot Panel toolbar.
