impose_boundary_conditions Subroutine

  1. type_euler-1D-caf.f90
  2. type_euler_1D_caf
  3. impose_boundary_conditions

private subroutine impose_boundary_conditions(self, primitive)

Impose boundary conditions.

The boundary conditions are imposed on the primitive variables by means of the ghost cells approach.

Arguments

Type IntentOptional AttributesName
class(euler_1D_caf), intent(in) :: self

Euler field.
real(kind=R_P), intent(inout) :: primitive(1:self%Np,1-self%Ng:self%Ni+self%Ng)

Primitive variables [1:Np,1-Ng:Ni+Ng].
