- *Select Text Font:* Opens a font selection dialog where the type and
size for the text editor and log font of the application can be set.
- *GUI update interval:* Allows to set the time interval between GUI
and data updates during a LAMMPS run in milliseconds. The default is
to update the GUI every 100 milliseconds. This is good for most cases.
For LAMMPS runs that run very fast, however, data may be missed and
through lowering this interval, this can be corrected. However, this
will make the GUI use more resources, which may be a problem on some
computers with slower CPUs. The default value is 100 milliseconds.
