Function/Subroutine Documentation

delete_force_energy()

subroutine mod_force_energy::delete_force_energy

(

type ( type_force_energy )

this

)

Initialization of one analytic of sogrid done in this subfunction, in module so_grid.

Deallocate all arrays.

Parameters

this	: instance of this class

Here is the caller graph for this function:

force_atom_uhbd()

subroutine mod_force_energy::force_atom_uhbd	(	real ( kind=8 ), dimension(3), intent(in)	x,
		real ( kind=8 ), dimension(3), intent(out)	f,
		type (type_grid ), intent(in)	tgrid
	)

Compute the derivative of the energy of position x.
Will be used to compute the force on an atom at position x
Pass an instance of type_grid as parameter, so it can apply to any grid
This version can deal with both uhbd and dtgrid. Overhead estimated to 10 %.

Parameters

x	: position of the atom
f	: return force ( rather derivative of the energy ) computed at x
tgrid	: instance of the grid used for computation
voxel	: voxel list containing 8 potential values

init_analytic()

subroutine mod_force_energy::init_analytic	(	type ( type_force_energy )	this,
		type ( array_protein_type ), intent(in)	tab_protein,
		real (kind=4), intent(in)	cut_off,
		real (kind=4), intent(in)	surf_cut,
		real (kind=4), intent(in)	h_anal,
		real (kind=8), intent(in)	surf_prefct,
		real (kind=4), intent(in), optional	opt_ionic,
		logical, optional, value	gouy_chapman
	)

Initialize specificaly analytical interactions.
.

Parameters

this	: instance of this class
tab_protein	: instance of mod_array_protein
cut_off	: indicates the maximum distance, half the box for sdamm, c-surface for sda_2proteins
surf_cut	: For a charged surface, its cut off is c-surf for 2prot, z extent for sdamm
h_anal	: bin size of analytical arrays
opt_ionic	: optional, used only for the ionic strength at the moment

init_force_energy()

subroutine mod_force_energy::init_force_energy	(	type ( type_force_energy )	this,
		type ( array_protein_type ), intent(in)	tab_protein,
		type ( type_calculation ), intent(in)	type_calc,
		logical, intent(in)	imetal
	)

Initilaize the oobject newer version, include asymetry, so need tab_protein to be general ( and sdamm case ) with sdamm need to modify shift, inter-type interactions, need type calculation.
