# massflow initialize command

Syntax

massflow initialize keyword

Set the value of parameters that affect the entire model, as well as parameters related to solving and saving.

base-fragment-size f

Set Base Fragment Size. The default value is 0.05.

compute-days i

Set number of days the massflow compute command is going to solve. Alternatively, compute-period can be set.

compute-period i

Set number of periods the massflow compute command is going to solve. Alternatively, compute-days can be set.

filename s

Set the filename prefix for generated save files. If not given, it will default to “massflow”.

imz-update i

Set the frequency of updating the IMZ geometries. By default, the IMZs are updated every two days.

layer-thickness f

Set slice thickness of the Isolated Movement Zone (IMZ). This is a multiplier relative to the Mine Block size. The default value is 0.5, meaning the slice thickness is half the Mine Block size.

massbalance-lower f

Set the lower limit for massbalance correction factor. Default is 0.1.

massbalance-upper f

Set the upper limit for massbalance correction factor. Default is 2.

percent-empty f

Set fraction of Mine Block volume that must be empty before adding air. The default value is 0.75.

rill-days i

Set how often, in days, rilling calculations are performed. Default is 1.

save-days i

Set how often, in days, save files will be created. Alternatively, save-period can be set.

save-period i

Set how often, in periods, save files will be created. Alternatively, save-days can be set.

tensile-ucs-ratio f

Set ratio of tensile strength to unconfined compressive strength. The default value is 0.1.
