Hello,
I am simulating a supersonic bow shock on air jet from nozzle inlet thrusting into the oncoming supersonic freestream with rhoCentralFoam k-ω SST model. The problem is while running the case simulation crashes at very early stage, i suspect that my boundary condition are incorrect specifically the supersonic freestream boundary conditions. My setup for p, T and U are as below.
p:

internalField   uniform 9831120;
boundaryField
{
    inlet
    {
        type        totalPressure;
        value       uniform 9831120;
        p0          uniform 9831120;
        psi         thermo:psi;
        gamma       1.4;
    }
    freestream
    {
        type        waveTransmissive;
        value       uniform 13800;
        field       p;
        psi         thermo:psi;
        lInf        0.43815;
        fieldInf    13800;
        gamma       1.4;
    }
    walls
    {
        type        zeroGradient;
    }
    axis
    {
        type        empty;
    }
    wedge1 {type wedge;}
    wedge2 {type wedge;}
}

T:

internalField   uniform 294;
boundaryField
{
    inlet
    {
        type           totalTemperature;
        value          uniform 294;
        T0             uniform 294;
        psi            thermo:psi;
        gamma          1.4;
    }
    freestream
    {
        type          zeroGradient;
    }
    walls
    {
        type          zeroGradient;
    }
...

U:

internalField   uniform (-694.404 0 0);
boundaryField
{
    inlet
    {
        type           zeroGradient;        
    }
    freestream
    {
       type            fixedValue;
       value           uniform (-694.404 0 0);
    }
    walls
    {
        type          noSlip;
    }
...

totalpressure is set for the nozzle inlet, To complement this boundary condition i use the zeroGradient boundary conditions for velocity inlet, also i don't know the value for velocity at nozzle inlet. The problem is with freestream boundary condition it is having the velocity in negative x-direction opposing the nozzle inlet also the internal field for U is right or wrong, I have attached the image of the geometry .
can anyone please help me out to set proper boundary condition.
