Subroutines

public subroutine atl_init_explicitEuler(me, minLevel, maxLevel)

Initialize explicit euler scheme for timestepping.

Arguments

TypeIntentOptionalAttributesName
type(atl_global_timestep_type), intent(inout) :: me

The datatype to initialize.
integer, intent(in) :: minLevel

The minimal level in the mesh.
integer, intent(in) :: maxLevel

The maximal level in the mesh.

private subroutine update_timestep_euler(me, timestepInfo)

Interface definition for levelwise updating of timestepping routine.

Arguments

TypeIntentOptionalAttributesName
class(atl_timestep_type), intent(inout) :: me

The type of your timestepping.
type(atl_local_timestep_type), intent(in) :: timestepInfo

Local timestepping information for that part of the mesh

private subroutine elemental_timestep_euler(me, state, cell, dof, sideFlux)

Interface definition for elementwise timestepping routine.

Arguments

TypeIntentOptionalAttributesName
class(atl_timestep_type), intent(inout) :: me

Description of the timestep integration method.
real(kind=rk), intent(inout) :: state(:,:,:)
