----------------------------------------------------------
The case concerns the unsteady one-dimensional flow that
occurs after the sudden break of a diaphragm. At the start
the pipe is divided into two halves by a diaphragm; the
gas on the left is at pressure 1.e7 and 800C and that on
the right at pressure 1.e5 and 200c.
The main purpose of this case is to demonstrate the use of
the built-in pressure source term in enthalpy/temperature
equation for MBFGE cases.
User can switch from the default colocated computational
algorithm (CCM) to the staggered one (STAG) by setting
LCCM = F.
By default the case is set as one domain case. User can
switch from that to two domain case by setting LMBLK=T.
