m_derived_variables Module Reference

This module features subroutines that allow for the derivation of numerous flow variables from the conservative and primitive ones. Currently, the available derived variables include the unadvected volume fraction, specific heat ratio, liquid stiffness, speed of sound, vorticity and the numerical Schlieren function. More...

Functions/Subroutines
subroutine, public	s_initialize_derived_variables_module ()
	Computation of parameters, allocation procedures, and/or any other tasks needed to properly setup the module.
subroutine, public	s_initialize_derived_variables ()
	Allocate and open derived variables. Computing FD coefficients.
subroutine, public	s_compute_derived_variables (t_step)
	Writes coherent body information, communication files, and probes.
subroutine	s_derive_acceleration_component (i, q_prim_vf0, q_prim_vf1, q_prim_vf2, q_prim_vf3, q_sf)
	This subroutine receives as inputs the indicator of the component of the acceleration that should be outputted and the primitive variables. From those inputs, it proceeds to calculate values of the desired acceleration component, which are subsequently stored in derived flow quantity storage variable, q_sf.
subroutine, public	s_finalize_derived_variables_module ()
	Deallocation procedures for the module.

Variables
Finite-difference coefficients
Finite-difference (fd) coefficients in x-, y- and z-coordinate directions. Note that because sufficient boundary information is available for all the active coordinate directions, the centered family of the finite-difference schemes is used.

s_derive_acceleration_component()

subroutine m_derived_variables::s_derive_acceleration_component	(	integer, intent(in)	i,
		type(scalar_field), dimension(sys_size), intent(in)	q_prim_vf0,
		type(scalar_field), dimension(sys_size), intent(in)	q_prim_vf1,

		type(scalar_field), dimension(sys_size), intent(in)	q_prim_vf3,
		real(kind(0d0)), dimension(0:m, 0:n, 0:p), intent(out)	q_sf )

This subroutine receives as inputs the indicator of the component of the acceleration that should be outputted and the primitive variables. From those inputs, it proceeds to calculate values of the desired acceleration component, which are subsequently stored in derived flow quantity storage variable, q_sf.

Parameters

i	Acceleration component indicator
q_prim_vf0	Primitive variables
q_prim_vf1	Primitive variables
q_prim_vf2	Primitive variables
q_prim_vf3	Primitive variables
q_sf	Acceleration component
