    1616Now, the psuedo-colors plots are in the original coordinate system, whereas the vector plot has been tilted to look like the colliding flow scenario. The psuedo plots show that over the forward shock, the velocity field becomes completely parallel to the shock front (i.e. the x-component vanishes). This forces vy to go to zero over the slow shock front to maintain symmetry (the flow solutions must be rotationally-invariant).

    18 Jonathan recently identified a way of decomposing the types of shocks in the simulations based on an eigen analysis. With this new code, we are able to see the different types of shocks present in the flow. For the MHD/infinite case, we see there are 5 wave fronts:

     22The left and right alfven modes appear to have 0 amplitude, and I am not completely sure why.
