The new remeshing capability in Zencrack 9.0-1 was an initial implementation onto which more capability has been added with the latest release, 9.3-1, having the ability to cater for multiple remeshing cracks.

The multi-crack remeshing capability in 9.3-1 includes a limitation that the remeshing regions of the cracks do not touch or overlap. Removing this limitation is the main development activity and a pre-cursor to further generalising the remeshing capability for multiple cracks. An example is shown below in which two cracks whose remesh regions are initially separate become embedded in a single remesh region after some growth has taken place.

A non-linear Kujawski-Ellyin crack growth law will be implemented as per the publication:
