FLAC 7.00 Update

Download Recent Update

Latest Version: 7.00.424 (Description)
Released On: Wednesday, May 11, 2016

Update Instructions

  1. Download the Microsoft installer (.msi) file. This is a full installation file; a previous version of the software is not necessary.
  2. Double-click on the file to begin the installation.


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).

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.

  • Allowed modifying FISH intrinsic variables DYTDEL and GWTDEL.
  • Fixed a couple of type mismatch in plot/print items(Hoek-Brown).
  • Modified FoS display format: the result dialog will display a floating number 7 digits wide, with 3 decimal places, and the number of decimal digits in printed FoS is increased from 2 to 3.
413 Dec 21, 2011
  • Fixed a bug in hardcopy plot generation when AUTONAME is active.
  • Added AUTONAME logic to EPS and DXF plot logic.

  • Correction to Cam-Clay model source to more appropriately set a lower bound for pre-consolidation pressure.
  • Fixed a variable initialization bug for two-phase flow logic.
412 Nov 22, 2011
  • Added CPOW as a built-in model in Creep configuration.
  • Fixed a bug for TPFlow. The bug was introduced in the modification to multhread stress calculation.
  • Updated COMMAND REFERENCE, CREEP MATERIAL MODELS and FLAC help manuals. In COMMAND REFERENCE, model and properties of CPOW were added. In CREEP MATERIAL MODELS, the model description and examples for CPOW were added. In FLAC help manual, the help on APPLY tool was modified to include applicability conditions of Free-field.
  • Changed 'hb_tension' to 'hbtension' in MHoek model (consistent with the description in the manuals).
