Hi all,

I am simulating flow over missile.
The freestream Mach no is 0.6, angle of attack is zero & solver is "rhoSimpleFoam"

dimensions [0 1 -1 0 0 0 0];

internalField uniform (205.9392 0 0);


bt // "bt" is the missile body&tail

type slip;

type zeroGradient;

type fixedValue;
value uniform (205.9392 0 0);

type empty;


At the tail fin face, the velocity magnitude(resultant) is zero at time=0. Why?
After the simulation also i get around 0.16m/s at the tail fin fact, but this is not correct. This may be because of the velocity field around fin face at time =0. Plz look at the snapshots.

Would you mind attaching the whole case files please ?
We don't see the mesh on your screenshots. For the moment, I am quite sure that your boundary conditions are missing something. However, your velocity BCs seem good.
