I tried running the forward-facing step tutorial case using sonicFoam and rhoCentralFoam for endTime = 20s with OF 4.1 on Ubuntu 14.04. At T = 20 the solutions have converged for both solvers. However the answers are different. The results don't agree well with the normal shock values for M = 3. Does anyone have any idea as to why this is so. Please see attached results.
