Finite Volume Discrete Ordinates Method. Solves the RTE equation for n directions in a participating media, not including scatter.
Available absorption models: greyMeanAbsoprtionEmission wideBandAbsorptionEmission
i.e. dictionary fvDOMCoeffs { nPhi1; // azimuthal angles in PI/2 on X-Y.(from Y to X) nTheta 2; // polar angles in PI (from Z to X-Y plane) convergence 1e-4; // convergence criteria for radiation iteration }
solverFreq 1; // Number of flow iterations per radiation iteration
The total number of solid angles is 4*nPhi*nTheta.
In 1D the direction of the rays is X (nPhi and nTheta are ignored) In 2D the direction of the rays is on X-Y plane (only nPhi is considered) In 3D (nPhi and nTheta are considered)
