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.
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_idx, 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_communicate_ib_forces (forces, torques)
	Swaps ownership of IBs and passes ownership of IBs to neighbor processors Reduces forces and torques across the local neighborhood without a global allreduce. Accumulation phase: 2 passes per dimension receiving from the low-index (-X) neighbor. Pass 1: add received values; save what was received as recv_snap. Pass 2: send current (post-pass-1) values; add received; subtract recv_snap to remove double-counting of the direct contribution already added in pass 1. Back-propagation phase: 2 passes per dimension receiving from the high-index (+X) neighbor, each overwriting local forces with the neighbor's accumulated total.
subroutine	m_ibm::s_handoff_ib_ownership ()
subroutine	m_ibm::s_get_neighborhood_idx (gbl_idx, neighborhood_idx)
subroutine	m_ibm::s_update_ib_lookup ()
impure subroutine, public	m_ibm::s_finalize_ibm_module ()
	Finalize the IBM module.
