Best FVS??
 

Hi,

I'm writing a code to handle oscillating objects at transonic speeds where there would be some shock-boundary layer interaction. Up to now, I'm not able to decide on the method to use for splitting the flux. Any suggestions??? Furthermore, I'm planning to use an explicit RK-4 to march in time with a multigrid and Im wondering whether the implicit unfactorized method would do better for the unsteady part (after reaching the steady state). Thanks, Michel
