Function Documentation

int NavierStokes3DLeftEigenvectors ( double *  u,
double *  L,
void *  p,
int  dir 
)

Compute the left eigenvections for the 3D Navier Stokes equations. This function just calls the macro _NavierStokes3DLeftEigenvectors_ and is not used by any functions within the 3D Navier Stokes module. However, it's necessary to define it and provide it to the the solver object (HyPar) so that it can then send it to interpolation functions for a characteristic-based reconstruction.

Parameters
uConserved solution at a grid point
LArray of size nvar^2 = 5^2 to save the matrix of left eigenvectors in (row-major format).
pObject of type NavierStokes3D with physics-related variables
dirSpatial dimension (x, y, or z)
