=== set spd ===

 '''set spd''' ''V<sub>n</sub>'' ''V<sub>p</sub>''
Overrides the speed of simulated particles. Input values:

{|
| ''V<sub>n</sub>''
| : speed of neutrons [in cm/s]
|-
| ''V<sub>p</sub>''
| : speed of photons [in cm/s]
|}

<u>Notes:</u>
*This option is intended for adjusting particle speeds for better visualization in [[#set tpa|track plot animations]].
**Adjusting the speed (obviously) results in incorrect estimates for all time constants.
**Exceeding the speed of light causes a fatal error in debug mode.
