Problem with SonicFoam

Hi all,

I am trying to simulate supersonic Inviscid flow over missile. I am using "sonicFoam" solver.

The velocity plots of OpenFoam & Fluent are matching but the pressure plots are not matching. OF results are half the value of Fluent results
Wat may be the problem..

I attached the case file

rhopSonicFoam & rhoSonicFoam are available for inviscid flow computation, but i am not able to calculate the lift & drag force.

No valid model for viscous stress calculation.

From function forces::devRhoReff()
in file forces/forces.C at line 115.

Regards
mecbe
