Collapsing feature of elastic vessels seems not functioning #7

Closed TomasKulhanek closed 9 years ago

TomasKulhanek commented 9 years ago

Collapsing feature of elastic vessels seems not functioning as elastic element goes into negative volume without a big force or nasty modeling. Attached example of 4 windkessel units in series with a pump. The fourth gets into negative volume after several seconds.

Please add the description of expected behaviour of the experiment.
