#FLAC3D SUPPORT TRIAL#
This paper presents the FLAC3D modelling of rock support arches in trial stope at Boliden's Garpenbergmine in Sweden. Rather, the record tracks the data file name, size, and last modified stamp for reference.2020 (English) In: 5th International Itasca Symposium - 2020 / Billaux, Hazzard, Nelson, & Schöpfer, 2020 Conference paper, Published paper (Refereed) Abstract These commands are considered to be already recorded in the data file itself. The state record does not record the contents of a data file that is executed. This state record can be played back directly using the program playback command, or they can be converted into an equivalent data file for later repetition or parameterization. These commands are available for review in the State Record Pane. Commands are recorded regardless of whether they are generated directly by the user or interactively by the user interface. This record is included in save files that represent the model state created using model save. All commands that occur in a given model state are recorded in the State Record. Operations that only affect the program or project state do not have this requirement and generally do not issue a command in the interface, although commands exist that only change those states. In FLAC3D, all operations that modify the current model state do so by issuing a command. The art of data file construction in FLAC3D is a matter of efficiently using all three paths to issue commands, as well as the save/restore system, to work through the problem. Instead, a final data file is arrived at in a stepwise fashion that is usually a blend of commands from the file itself and/or other data files, the command prompt, and the user interface, not to mention the number of "drafts" that occur in refining the modeling approach taken to best represent the problem. Though typing a data file in its entirety prior to any command processing is possible, in practice this is rarely done. Model construction in FLAC3D is thus a matter of data file construction. This is both more efficient than either the command prompt or mouse/keyboard commands-either of which is limited to issuance of one command at a time-and has the added advantage of providing a beginning-to-end, readable problem representation. The data file is essentially a batch file, that is, a list of commands that can be issued and processed in unbroken sequence. However, there is a third place where commands are saved/recorded: the data file. There is noĭifference between the commands as issued from one place or the other, merely the matter ofĮfficiency or speed in the issuing, and user preference. In a number of cases, they are generated interactively by the user interface. Those commands can be issued from the command prompt, or, Is described in the t1_06equilibrium and Further Discussion: Step to Equilibrium topics.įLAC3D is a command-driven program.

The solution is reached after a series of computational steps. (This is a large topic see theįLAC3D Theory and Background section.) FLAC3D uses an explicit time-marching method to solve theĭiscretized equations. The actual solution of the problem is different for an explicit program like FLAC3D than it isįor conventional implicit-solution programs.
