FLAC 6.00 Modification List (Type PRINT VERSION to check version number.)
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)
