This image shows the extendedMerlin model venting hydrogen to space at the beginning of a run.

The model was filled to 1 bar of hydrogen before the run. This appears to be a requirement for the equations to have something to chew on.

We have initiated a feed of new hydrogen at the intake at the far left, and simultaneously we have opened a valve to drain hydrogen out of the outlets.

Only one outlet is participating in the drain at this point. It is possible to see hydrogen draining from the heat pipe to the outlet.

The images here were obtained from a test run of extendedMerlin that was supposed to show no activity at all.

The entire model was initialized to 300 Kelvin at 1 bar of hydrogen.

No energy was fed into the model. Nothing should have happened. Instead, activity occurred in the vicinity of the original engine.

This view shows the engine compartment in Composite Colors view...

The display is in wireframe which increases the lighting level slightly
