shock tube: problem initiation -- CFD Online Discussion Forums

Gareth Guest Posts: n/a	I have tried to model a shock tube, but am struggling to get the initial conditions right, because in order to define the different pressures, it seems one has to define 2 fluids, and it seems that one cannot have different fluids in adjacent cells. I have tried defining baffle cells between them and then removing the baffles (using the events module), but this doesn't seem to work either. Has anyone succeeded in doing this kind of thing without using subroutines? (I don't have the fortran compiler) Any feedback would be appreciated. Gareth
