[Syntax:]

fix ID group-ID elstop Ecut file keyword value ... :pre

fix ID group-ID electron/stopping Ecut file keyword value ... :pre

ID, group-ID are documented in "fix"_fix.html command :ulb,l

elstop = style name of this fix command :l

electron/stopping = style name of this fix command :l

Ecut = minimum kinetic energy for electronic stopping (energy units) :l

file = name of the file containing the electronic stopping power table :l

zero or more keyword/value pairs may be appended to args :l

  {region} value = region-ID

    region-ID = region, whose atoms will be affected by this fix

  {minneigh} value = minneigh

    minneigh = minimum number of neighbors for atoms to have elstop applied :pre

    minneigh = minimum number of neighbors an atom to have stopping applied :pre

:ule

[Examples:]

fix el all elstop 10.0 elstop-table.txt

fix el all elstop 10.0 elstop-table.txt minneigh 3

fix el mygroup elstop 1.0 elstop-table.txt region bulk :pre

fix el all electron/stopping 10.0 elstop-table.txt

fix el all electron/stopping 10.0 elstop-table.txt minneigh 3

fix el mygroup electron/stopping 1.0 elstop-table.txt region bulk :pre

[Description:]

\vec\{F\}_i = \vec\{F\}^0_i - \frac\{\vec\{v\}_i\}\{\|\vec\{v\}_i\|\} \cdot S_e

\end\{equation\}

where \(\vec\{F\}_i\) is the resulting total force on the atom. \(\vec\{F\}^0_i\)

is the original force applied to the atom, \(\vec\{v\}_i\) is its velocity and

\(S_e\) is the stopping power of the ion.

where \(\vec\{F\}_i\) is the resulting total force on the atom.

\(\vec\{F\}^0_i\) is the original force applied to the atom, \(\vec\{v\}_i\) is

its velocity and \(S_e\) is the stopping power of the ion.

NOTE: In addition to electronic stopping, atomic cascades and irradiation

simulations require the use of an adaptive timestep (see

setting {minneigh} to zero and using the {region} keyword. This is necessary

when running simulations of cluster bombardment.

If the {region} keyword is used, the atom must also be in the specified geometric

"region"_region.html in order to have electronic stopping applied to it. This is

useful if the position of the bulk material is fixed. By default the electronic

stopping is applied everywhere in the simulation cell.
