Fix reaxff/bonds command
WebThe mol keyword should be used when other commands, such as fix deposit or fix pour, add molecules on-the-fly during a simulation, and you wish to constrain the new molecules via SHAKE.You specify a template-ID previously defined using the molecule command, which reads a file that defines the molecule. You must use the same template-ID that the … WebFor all versions of the fix, the keyword-value ffield on enables the finite-field mode (Dufils, Tee), which uses an electric field across a periodic cell instead of non-periodic boundary conditions to impose a potential difference between the two electrodes bounding the cell.The fix (with name fix-ID) detects which of the two electrodes is “on top” (has the larger …
