DMR Problem Set up

For the following tests we use outflow boundary conditions on the right, post shock BC's on the left, and symmetric slip bc's on the bottom and on the GFM boundary. In order to minumize boundary errors on the bottom boundary, this problem was solved in a rotatated frame of reference, yet, this made a time dependent BC on the top boundary a nesscessary addition. On the top, left of the incident shock is (in the lab frame) post-shock, and right of the incident shock is pre-shock.

The gas for this test was a Perfect Gas (constant specific heat, viscosity, and conductivity

%MATHMODE{\theta_{wedge} = 36 degrees, \quad \mu=1.73*10^{-5} Pa*sec, \quad k = 0.0257 W/(m*K)}% %MATHMODE{\quad m = 0.0288288 kg/mol,\quad \gamma = 1.4, \quad M=4.5}% %MATHMODE{\quad T_0=300 K, \quad p_0 = 2000 Pa, \quad t_{final}=4*10^{-5} sec}%

where the 0 subsript denotes the pre-shock flow (which in the shock stationary frame of reference has a Mach number of 4.5).
