Robert Caulk proposed the following answer:
Hello Azim,

The duration of a simulation depends entirely on the simulation you plan
to run. Triaxial? Uniaxial? Something else? Is it concluded by reaching
a certain simulation time? Strain value? Something else?

If you know the number of required iterations, you could simply start
the simulation with however many particles you wish, then take your
required desiredIteration (iter) and divide it by O.speed (iter/second):

desiredIteration/O.speed = real-world time to get to desiredIteration
(seconds)

If you have a desiredModelTime you could use O.realtime (seconds) and
O.time (modelSeconds):

(O.realtime/O.time) * desiredModelTime = real-world time to get to
desiredModelTime

If you have a desiredStrain (strain), and you are imposing a constant
strainRate (strain/modelSecond) you could use:

(desiredStrain / strainRate) * (O.realtime / O.time) =  real-world time
to get to desiredStrain

I hope you see the pattern! I cannot cover all possible simulation
conclusion types.

Cheers,

Robert
