\(rgc\)

random generation of solvent configurations
Current version: 2024.01 (shared with CC-BY-NC license). See also all python tools and software pages.

Solute / solvent descriptions

The Solute and Solvent blocks follow the guidelines for the EXTERNAL block in DRF90, and should be indicated with $SOLUTE and $SOLVENT, as if they were namelists.

Parameters

parameter
description
default
\(boxr\)
Radius of spherical box (with IBOX=1) or size of cubic box (with IBOX=2)
0.0
\(boxx\)
Size of box in X-direction
0.0
\(boxy\)
Size of box in Y-direction
0.0
\(boxz\)
Size of box in Z-direction
0.0
\(density\)
Macroscopic density (kg/l) to be realized
0.0
\(ibox\)
Kind of image box used;
1
\(ifull\)
Parameter specifying if all atoms or only c.o.m. of molecules should be inside box:
  • 0: All atoms should be inside box
  • 1: C.o.m. of molecules should be inside box
0
\(inear\)
Number of near molecules to keep track of
3
\(iradex\)
Type of atomic radii used:
  • 1: "Optimal" radii for RGC
  • 4: Frecer's charge dependent radii (H-Ar)
  • 5: Miertus's charge dependent radii (H-Ar)
Note: This option will always overrule any radius specified in the SOLUTE/SOLVENT block.
If no radius is available for an atom with option 4/5, then:
- if a nonzero radius is given in the SOLUTE/SOLVENT block, that one will be used,
- else a tabulated value will be used (Bondii for some atoms; -99.999 if unknown => this will make the program stop, and you will have to specify a radius in the SOLUTE/SOLVENT block).
1
\(iunit\)
Unit for atomic coordinates given in the input:
  • 0: Atomic units (Bohrs)
  • 1: Angstrom
0
\(mxtry\)
Maximum number of tries
100000
\(nsolute\)
Number of solutes to put
0
\(nsolvent\)
Number of solvents to put
0
\(overlap\)
Parameter indicating how much overlap there may be between the two closest atoms
0.2
\(vdwfact\)
Parameter to relate "Sum of atomic volumes" to "Total volume" (see this paper)
