template<class T, class U> AMREX_GPU_HOST_DEVICE AMREX_INLINE void conservative_to_primitive (int i, int j, int k, Array4< Real const > const &uin, Array4< Real const > const &Bx, Array4< Real const > const &By, Array4< Real const > const &Bz, Array4< Real const > const &Erin, Array4< Real const > const &lam, T &q, U &qaux, const bool fill_passives)

Convert conservative variables to primitive variables. The method is templated so that q/qaux can either be either Array4 or Array1D.

Parameters:

  • i – x index

  • j – y index

  • k – z index

  • uin – input conserved state

  • Bx – x-component of magentic field (if USE_MHD=TRUE)

  • By – y-component of magentic field (if USE_MHD=TRUE)

  • Bz – z-component of magentic field (if USE_MHD=TRUE)

  • Erin – radiation energy (if USE_RAD=TRUE)

  • lam – radiation flux limiter (if USE_RAD=TRUE)

  • q – output primitive state

  • qaux – output auxiliary quantities
