angle_style hybrid command :h3
|
|
|
|
[Syntax:]
|
|
|
|
angle_style hybrid style1 style2 ... :pre
|
|
|
|
style1,style2 = list of one or more angle styles :ul
|
|
|
|
[Examples:]
|
|
|
|
angle_style hybrid harmonic cosine
|
|
angle_coeff 1 harmonic 80.0 1.2
|
|
angle_coeff 2* cosine 50.0 :pre
|
|
|
|
[Description:]
|
|
|
|
The {hybrid} style enables the use of multiple angle styles in one
|
|
simulation. An angle style is assigned to each angle type. For
|
|
example, angles in a polymer flow (of angle type 1) could be computed
|
|
with a {harmonic} potential and angles in the wall boundary (of angle
|
|
type 2) could be computed with a {cosine} potential. The assignment
|
|
of angle type to style is made via the "angle_coeff"_angle_coeff.html
|
|
command or in the data file.
|
|
|
|
In the angle_coeff command, the first coefficient sets the angle style
|
|
and the remaining coefficients are those appropriate to that style.
|
|
In the example above, the 2 angle_coeff commands would set angles of
|
|
angle type 1 to be computed with a {harmonic} potential with
|
|
coefficients 80.0, 1.2 for K, r0. All other angle types (2-N) would
|
|
be computed with a {cosine} potential with coefficient 50.0 for K.
|
|
|
|
An angle style of {none} can be specified as an argument to
|
|
angle_style hybrid and the corresponding angle_coeff commands, if you
|
|
desire to turn off certain angle types.
