TALK=T;RUN(1,1) DISPLAY ---------------------------------------------------------- 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. ---------------------------------------------------------- ENDDIS ************************************************************ Group 1.
