FLAC 7.00, Current Version

Pre-requisites Update Instructions

Revision History GIIC Revision History

Starting with subversion 395, an update to the Microsoft (R) Visual C++ 2005 Runtime is REQUIRED. (The current subversion of the code update available here appears at the end of the Revision History — see link above.) If not present, on startup the code will return an error message similar to "The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem" (on Windows XP or later) or it will complain of missing DLLs (Windows 2000).

Visual C++ 2005 Runtime

The installation process need only be performed once; subsequent updates to FLAC will not require these steps to be repeated (updates to the runtime released by Microsoft may need to be installed).

Users of Windows XP should also update the Windows installer to Version 4.0 or newer.

Changes listed are included in FLAC600.EXE.

Sub-Version  Date             Description
    Number

375      10/16/07  Version 6.00 prereleased to Itasca website.

376      11/27/07  This version allows direct access to the added gridpoint
                   mass to account for hydrodynamic pressures applied to
                   concrete dams.  The FISH variable, GMSCL, is available to
                   store the added mass.  The FISH function WESTERGAARD.FIS is
                   provided to apply hydrodynamic pressures to a vertical face
                   of a concrete dam.  The attached document describes this
                   approach.

378      01/16/08  This version pre-releases automatic remeshing (or
                   rezoning) logic for large-strain models, including dynamic
                   simulations. A PDF file documenting the logic and a
                   few demo examples and corresponding data files are included
                   in the downloadable package. Note that the rezoning logic
                   is only working in command-driven mode at the present stage.

380      03/17/08  This version pre-releases a generic grid generation tool in
                   the graphical user interface.

387      09/25/08  This is FLAC6.00 release version.

388      11/18/08  GIIC modification (see subversion 418)

389      12/15/08  Extended auto-remeshing logic to advect extra variables. An
                   extra variable can be treated as float-type zone-based
                   quantity, int-type zone-based quantity or gp-based quantity,
                   correspondingly, the advection rule will be volume-averaging
                   ("vol_avg"), majority-rule ("maj_rul") or interpolation
                   ("interpo"). The volume-averaging is the default (a demo
                   data file can be found in the sub-folder "data" within the
                   downloaded package).

                   Improved path parsing logic to resolve the problem of path
                   with parenthesis typically encountered when FLAC6.00 is
                   installed into a 64-bit Vista system.

                   Issued an error message and prevented FLAC shut down when
                   failing to overwrite an open file.

                   Fixed SYS DOS command.

                   GIIC modification (see subversion 422)

390      12/23/08  Changed the printout information in the startup window
                   to show available options in the key.

                   Improved ATTACH logic to remove attached gridpoints
                   from the attach list if these gridpoints are associated
                   with zones that are nullified.

                   Added a new command PLOT STRUCT BEAM (or LINER) STATE
                   to plot the yielding status (yielding in
                   compression or tension) for beam/liner nodes.

                   GIIC modification (see subversion 425)

391      01/05/09  Improved ATTACH logic to remove self-attached gridpoints
                   from the attach list if none of their neighboring
                   gridpoints is in the attach list.

                   GIIC modification (see subversion 426)

393      04/08/09  Added PROFILE keyword as symnonym for LINE to avoid conflict
                   with liner element when creating profile plot.

                   Added ATTACH REMOVE i i1 j1 j i2 j2   command.

                   Fixed error in the large strain unit normal rotation
                   calculation in the CPPUDM UBIQUITOUS constitutive model.

                   GIIC modifications (see subversion 431)

394      09/03/09  Improved liner logic: the same formulation is used for the
                   non-elastic behavior of beam elements in UDEC and liner elements
                   in FLAC. The failure surface is represented by 2 lines in the
                   M-N plane, which are defined by the specified compressive and
                   tensile strengths. In the original routines, any point falling
                   outside the failure surface would be brought back to the
                   failure surface along a radial line. This implied corrections
                   both in the moment and the axial force. Since the axial force
                   should be uniform along the element, an inconsistency in the
                   corrected axial forces at both element nodes would result.
                   The change that was made involves a different correction: the
                   axial force is not changed and only the moment is reduced to
                   bring the point back to the failure surface. For most practical
                   cases, no major differences in the results are expected. If the
                   user reduces the strength at some stage, so that a M-N point
                   would suddenly be far outside the failure surface, a somewhat
                   different response may result. Also for stress paths crossing
                   the tensile or low compression segments of the M-N diagram
                   some differences may occur.

                   Tracked compressive/tensile yielding state for appropriate
                   structure elements such as beam,cable,liner,rockbolt and
                   strip (see "State_RockBolt.dat" in "data" folder).

                   Converted spare structural element and node offsets to extra
                   offsets:'kelsp2'->'kelex1', 'kelsp3'->'kelex2','kndsp7'->'kndex1',
                   'kndsp8'->'kndex2' (see updated "str.fin" in "data" folder).

                   Added new keywords 'nd_ex1' and 'nd_ex2' to plot extra nodal
                   offsets; 'el_ex1' and 'el_ex2' to plot extra element offsets.
                   (see "fiberstress.dat" in "data" folder)

                   Suppressed the misleading error message when attempting to
                   delete a non-existent file in DOS window using SYS DELETE
                   command.

                   Automatically loaded DLL file from "exe\plugins\models" folder
                   when FLAC starts up.

                   GIIC modifications (see subversion 432)

395      02/16/10  Corrected saturation adjustment in attached grids (see
                   "attfluid.dat" in "data" folder).

396      03/12/10  Corrected a FISH socket communication error.
                   Extended SET SYMSCALE to apply to plot item MARK.

397      08/18/10  Optional keyword phrase "region table n" now applies to
                   GROUP command.

398      09/29/10  Correction to fluid flow logic for desaturation analysis
                   with high water bulk modulus. (test "desat.dat" in
                   "data" folder)

                   Fixed a format error for STEP info in DXF plot.

399      06/22/11  Correction to fluid flow logic to prevent updating
                   saturation induced by mechanical volume change at GP
                   with zero saturation, to prevent the change of pore
                   pressure at attached GP with fixed pore pressure condition.

401      12/23/11  Correction to Cam-Clay model source to more appropriately
                   set a lower bound for pre-consolidation pressure.
