Hi,
I've tried to use AeroFoam 1.7.1 solver for the OpenFoam 1.7.1 tutorial case ObliqueShock, and I 've done all the correctoins which are given in the AEROFOAM QUICK START paper www.aero.polimi.it/freecase/?download=AeroFoam_QuickStart.pdf
but after entering AeroFoam I see the following message:
vadim.vorobyov@oslo:~/OF171/compressible/aeroFoam/forwardStep$ AeroFoam
