What's New in Zencrack?
Zencrack version 8.2-2 was finalised on 11 December 2017
Version 8.2-2 is a minor upgrade with a small number of changes and bug fixes compared to version 8.2-1.
The ** marker used to indicate the active mesh viewport when multiple mesh viewports are available is moved from the title bar of the viewport to the upper left corner of the viewport window. This addresses a limitation in the original method that prevented the marker being removed for floated viewports.
A new element set is generated for each crack front containing all the elements in the rings around the crack front.
For Abaqus and Ansys the set/component name is CRACKxxxrings where xxx is the crack front number e.g. CRACK001rings.
For NX Nastran the numbered set is 9090xxx.
NX Nastran interface
In the NX Nastran interface a limitation existed when gluing some large crack-blocks to the surrounding mesh because NX Nastran 10 and 11 do not allow the use of collapsed hex element faces on a surface definition. NX Nastran 12 has an enhancement in the surface definitions to resolve this limitation.
Zencrack 8.2-2 has a modification to allow the full surface to be defined, including the collapsed faces, when NX Nastran 12 is used. A warning is issued if collapsed elements are required on a surface definition when using NX Nastran 10 or 11.
