Version 7.4 releases

Version 7.4a

Version 7.4a was finalised on 28 July 2006.

Available for PC Windows 2000/XP/XP 64, HP-UX, IBM AIX and Silicon Graphics IRIX. More information.

A full list of new functionality is available from the "what's new?" page.

The following bugs are fixed in this release:

ZENCR332 - raw contour values reported by utility program PROCESS are all zero in v7.4
ZENCR331 - error control scheme does not control step sizes between f.e. analyses correctly if results sets exist that are not used in load systems
ZENCR330 - possible Fortran error when using a user defined crack front
ZENCR329 - possible Fortran error if a job is re-run and previous output is set read-only
ZENCR328 - problem with user subroutine user_constraint
ZENCR327 - possible error if all faces of an element or element set are to be updated on a single *SURFACE data line (Abaqus only)
ZENCR326 - possible error processing the rep file with utility program PROCESS
ZENCR325 - jobs with very large coordinates fail after the f.e. analysis (Ansys interface only)
ZENCR324 - incorrect results for an embedded crack front (MSC.Marc interface only)
ZENCR323 - extrapolation issue for displacement based results on crack fronts with one element along the crack front
ZENCR322 - problem with an argument in the call to user subroutine user_transfercf
ZENCR321 - j-integral data may be not be processed correctly if K FACTORS are requested from the f.e. analysis (Abaqus only)
ZENCR320 - use of Zencrack with Abaqus 6.5-4 (or later)
ZENCR319 - unexpected error 4034 in an analysis with a user defined initial crack front
ZENCR318 - unexpected error 4077 in an analysis with a user defined initial crack front
ZENCR317 - crack fronts not identified correctly for some reverse crack-block configurations
ZENCR316 - biasing of nodes in the crack front element rings may cause a growth analysis to fail
ZENCR315 - documentation of the option *MAPPING, NORMAL=yes/no is misleading
ZENCR314 - use of *MAPPING, NORMAL=yes may cause an analysis to give an unexpected error
ZENCR302 - minor error in the runzcr7x script file for Unix installations
ZENCR293 - minor format issue in the .rep file

ZENCR311 - input limitation for Paris and Walker crack growth options
ZENCR310 - some crack face nodes may be reported as "closed" when they are "open"
ZENCR309 - documentation - minor error in an equation

ZENCR300 - possible error when using *MAPPING,MIDSIDE=CURVED
ZENCR266 - documentation - minor error in description of the THRESHOLD keyword.
ZENCR157 - some *BOUNDARY updates may not behave as expected (Abaqus only)
