Function/Subroutine Documentation

compute_ugradphi_weno5()

subroutine mod_lsm_compute_ugradphi::compute_ugradphi_weno5	(	double precision, dimension(nx,ny,nz), intent(in)	phi,
		type(t_face_field), intent(in)	velocity,
		double precision, intent(in)	time_step,
		double precision, dimension(nx,ny,nz), intent(inout)	ugradphi,
		integer, dimension(nx,ny,nz), intent(in)	band
	)

Parameters

[in]	phi	the level set
[in]	velocity	the velocity field on faces
[in,out]	ugradphi	the resulting field
[in]	band	the band (integers)
[in]	time_step	the time step (unused, but might be used for high-order fluxes)

Note

A high-order (WENO5) scheme is used inside the close band (band(i,j,k)={1,2}). A first order scheme is used outside (band/={1,2}).
