Hello Foamers,

I am trying to use supersonic compressible solver (rhoCentralFoam/sonicFoam) to simulate flow across a bullet, which has a rotational motion (dynamicMeshDict). The bullet used is a stl file, henceforth I used snappyHexMesh to generate the Mesh. The arbitrary mesh interface (AMI) is also introduced in the simulation to enable simulation across disconnected, adjacent, mesh domains.

The boundary condition used for pressure (p) is:
For inlet, walls, bullet wall I have used "zeroGradient" boundary condition.
For outlet I have used "waveTransmissive" boundary condition.
For AMI I have used "cyclicAMI" boundary condition.

The boundary condition used for velocity (U) is:
For inlet "supersonicFreestream" is used.
For outlet "inletOutlet" is used.
For bullet "movingWallVelocity" is used.
For walls "zeroGradient" is used.
For AMI "cyclicAMI" is used.

The boundary condition used for temperature (T) is:
For inlet and outlet "inletOutlet" is used.
For walls and bullet wall "zeroGradient" is used.
For AMI "cyclicAMI" is used.

The fvSchemes and FvSolution that I have used is same as that of the tutorials that are provided for rhoCentralFoam and sonicFoam.

But when I try to launch the simulation, it runs for few iterations and finally fives the error mentioned below

Code:
--> FOAM FATAL ERROR: 
Negative initial temperature T0: -26.69115

    From function Foam::scalar Foam::species::thermo<Thermo, Type>::T(Foam::scalar, Foam::scalar, Foam::scalar, Foam::scalar (Foam::species::thermo<Thermo, Type>::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo<Thermo, Type>::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo<Thermo, Type>::*)(Foam::scalar) const) const [with Thermo = Foam::hConstThermo<Foam::perfectGas<Foam::specie> >; Type = Foam::sensibleInternalEnergy; Foam::scalar = double; Foam::species::thermo<Thermo, Type> = Foam::species::thermo<Foam::hConstThermo<Foam::perfectGas<Foam::specie> >, Foam::sensibleInternalEnergy>]

Would somebody be kind enough to help me solve this problem.
