fluid_scheme_compressible_update_physical_flux()

subroutine fluid_scheme_compressible::fluid_scheme_compressible_update_physical_flux ( class(fluid_scheme_compressible_t), intent(inout)  this )

private

Decides whether the physical Navier-Stokes viscous and heat fluxes have to be evaluated at all, by testing \( \max_i |\mu_i| \) and \( \max_i |\kappa_i| \) against zero.

On a device backend the reduction runs as a kernel over the device resident arrays. Inspecting the host mirrors mux and kappax instead would be wrong as well as slow: field_cfill, and the device_math routines a user file calls, only write x_d, so the host copies stay at their initial zero and the solver would silently degrade to Euler.

The reduction is global, so all ranks agree on the branch taken even when the viscosity is non-zero on only some of them.

Parameters

this	The compressible fluid scheme object

Definition at line 481 of file fluid_scheme_compressible.f90.
