Functions/Subroutines
impure subroutine, public	s_initialize_derived_variables_module
	Computation of parameters, allocation procedures, and/or any other tasks needed to properly setup the module.
impure subroutine, public	s_initialize_derived_variables
	Allocate and open derived variables. Computing FD coefficients.
subroutine, public	s_compute_derived_variables (t_step, q_cons_vf, q_prim_ts1, q_prim_ts2)
	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.
impure subroutine	s_derive_center_of_mass (q_vf, c_m)
	This subroutine is used together with the volume fraction model and when called upon, it computes the location of of the center of mass for each fluid from the inputted primitive variables, q_prim_vf. The computed location is then written to a formatted data file by the root process.
impure 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.

Function/Subroutine Documentation

◆ s_compute_derived_variables()

subroutine, public m_derived_variables::s_compute_derived_variables	(	integer, intent(in)	t_step,
		type(scalar_field), dimension(:), intent(inout)	q_cons_vf,
		type(vector_field), dimension(:), intent(inout)	q_prim_ts1,
		type(vector_field), dimension(:), intent(inout)	q_prim_ts2 )

Writes coherent body information, communication files, and probes.

q_cons_vf	Conservative variables
q_prim_ts1	Primitive variables at time-stage 1
q_prim_ts2	Primitive variables at time-stage 2

◆ 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_vf2,
		type(scalar_field), dimension(sys_size), intent(in)	q_prim_vf3,
		real(wp), 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

◆ s_derive_center_of_mass()

impure subroutine m_derived_variables::s_derive_center_of_mass	(	type(scalar_field), dimension(sys_size), intent(in)	q_vf,
		real(wp), dimension(1:num_fluids, 1:5), intent(inout)	c_m )

This subroutine is used together with the volume fraction model and when called upon, it computes the location of of the center of mass for each fluid from the inputted primitive variables, q_prim_vf. The computed location is then written to a formatted data file by the root process.
