PetscRiemannFn#

A prototype of a pointwise function that can be passed to, for example, PetscDSSetRiemannSolver()

Synopsis#

typedef void PetscRiemannFn(PetscInt dim, PetscInt Nf, const PetscReal x[], const PetscReal n[], const PetscScalar uL[], const PetscScalar uR[], PetscInt numConstants, const PetscScalar constants[], PetscScalar flux[], void *ctx);

Calling Sequence#

  • dim - the coordinate dimension

  • Nf - The number of fields

  • x - The coordinates at a point on the interface

  • n - The normal vector to the interface

  • uL - The state vector to the left of the interface

  • uR - The state vector to the right of the interface

  • numConstants - number of constant parameters

  • constants - constant parameters

  • flux - output array of flux through the interface

  • ctx - optional user context
