diff¶
Todo
This command has not yet been ported to the new APBS syntax (see YAML- and JSON-format input files).
Specify the diffusion coefficients for each molecule in the system for a PB-(S)AM Brownian dynamics calculation.
diff {type} {dTrans} {dRot}
type
a string indicating the molecule dynamics type
stat
- Stationary.
rot
- Object is fixed but rotates
move
- Object moves and rotates.
dTrans
- Translational diffusion coefficient in units of Å2 ps-1.
Used only with the
move
keyword. dRot
- Rotational diffusion coefficient.
Used with the
move
androt
keywords.
Todo
What are the units for dRot
?
Documented as https://github.com/Electrostatics/apbs/issues/486
Note
The order of these keywords is expected to be identical to the order of the molecules in the READ section.
Todo
Add a mol id
flag rather than have an implicit ordering of the diff
keywords.
