Modules
module	m_ibm
	Ghost-node immersed boundary method: locates ghost/image points, computes interpolation coefficients, and corrects the flow state.

Functions/Subroutines
impure subroutine, public	m_ibm::s_initialize_ibm_module ()
	Allocates memory for the variables in the IBM module.
impure subroutine, public	m_ibm::s_ibm_setup ()
	Initializes the values of various IBM variables, such as ghost points and image points.
subroutine, public	m_ibm::s_ibm_correct_state (q_cons_vf, q_prim_vf, pb_in, mv_in)
	Update the conservative variables at the ghost points.
impure subroutine, private	m_ibm::s_compute_image_points (ghost_points_in)
	Compute the image points for each ghost point.
subroutine, private	m_ibm::s_find_num_ghost_points (num_gps_out)
	Count the number of ghost points for memory allocation.
subroutine, private	m_ibm::s_find_ghost_points (ghost_points_in)
	Locate all ghost points in the domain.
subroutine, private	m_ibm::s_compute_interpolation_coeffs (ghost_points_in)
	Compute the interpolation coefficients for image points.
subroutine, private	m_ibm::s_interpolate_image_point (q_prim_vf, gp, alpha_rho_ip, alpha_ip, pres_ip, vel_ip, c_ip, r_ip, v_ip, pb_ip, mv_ip, nmom_ip, pb_in, mv_in, presb_ip, massv_ip)
	Interpolate primitive variables to a ghost point's image point using bilinear or trilinear interpolation.
impure subroutine	m_ibm::s_update_mib (num_ibs)
	Resets the current indexes of immersed boundaries and replaces them after updating the position of each moving immersed boundary.
subroutine	m_ibm::s_compute_ib_forces (q_prim_vf, fluid_pp)
	Compute pressure and viscous forces and torques on immersed bodies via volume integration.
impure subroutine, public	m_ibm::s_finalize_ibm_module ()
	Finalize the IBM module.
subroutine	m_ibm::s_compute_centroid_offset (ib_marker)
	Computes the center of mass for IB patch types where we are unable to determine their center of mass analytically. These patches include things like NACA airfoils and STL models.
subroutine	m_ibm::s_compute_moment_of_inertia (ib_marker, axis)
	Computes the moment of inertia for an immersed boundary.
subroutine	m_ibm::s_wrap_periodic_ibs ()
	Wrap immersed boundary positions across periodic domain boundaries.
subroutine	m_ibm::s_cross_product (a, b, c)
	Compute the cross product c = a x b of two 3D vectors.

Variables
type(integer_field), public	m_ibm::ib_markers
type(ghost_point), dimension(:), allocatable	m_ibm::ghost_points
integer	m_ibm::num_gps
	Number of ghost points.
logical	m_ibm::moving_immersed_boundary_flag
