FLAC3D 3.00 Modification List (Type PRINT VERSION to check version number.) Changes listed are included in F3300.EXE. Sub-Version Date Description Number 251 10/1/04 Version 3.00 released as "pre-release" to users. 252 11/08/04 Coupled unsaturated fluid flow logic bug fix. A slow build up of pore pressure occurred at the water table level when the water table level corresponded exactly to the position of a gridpoint. 254 12/01/04 nx, ny, nz properties were ignored when they were being set in the anisotropic and orthotropic models. Fixed an error in the orthotropic model rotation matrix. 255 01/24/05 When a component of velocity was removed at a gridpoint (e.g., "apply remove zvel") and other applied velocity components existed at that gridpoint then a fatal error would result when cycling. 256 02/21/05 With the radcylinder gridding primitive, when an odd number of zones was specified for the 3rd size parameter and the fill option was used (e.g., gen zone radcyl size 2 2 3 2 fill) then the zones would not match between the radcylinder opening and the filled cylinder. Added z_frr and z_fri for FISH access to the full rotation rate and full rotation increment tensors (equation 1.50 of the v2.10 Theory and Background manual). 257 03/14/05 Pile elements did not do bending yielding calculations unless the rockbolt property was turned on. Piles now always perform the bending yielding calculations regardless of the rockbolt property setting.
