Summary for version 7.3

General

• The maximum allowed model size is increased to 75000 elements and 375000 nodes.
• There is a significantly reduced memory requirement for all Zencrack jobs.
• The overwrite option to delete existing job files is improved.
• A large number of error and warning messages have been updated and improved.
• A new utility program "process" replaces the previous utility "growth". This utility generates a comma separated variable file (.csv) ready for import into a spreadsheet and provides improved post-processing functionality.
• Utility program "3dmesh" is updated as to includean Ansys format output option. In addition, other improvements have been made in the choice of 2 or 3 noded element types and the offset of node and element number (to allow combination of multiple sets of profiles).

Abaqus interface

• Abaqus user subroutine zcr-ctint is provided (a urdfil routine) to allow extraction of Ct-integral values from the .fil file in addition to the existing option of extracting the values from the .dat file.

Ansys interface

• Temperature interpolation is now possible into the crack-blocks for a temperature distribution defined at all nodes in the uncracked mesh.
• If there are temperatures in the f.e. analysis then the temperatures at crack front nodes can be extracted for use in processing the results.
• Transition elements can be defined when using surface based tying to incorporate crack-blocks into a model.
• Ansys solid model options can be used in the uncracked mesh batch file.
