CZMESH is used on a mesh with shared nodes at the interface.
specified, the CZMESH command creates/meshes interface
elements (INTER202, INTER203, INTER204, INTER205) along the boundary between the two components or groups of elements.
The elements in each of the components or groups of elements share nodes with each other and also with the interface elements. This one-element thick boundary of interface elements splits the body between the two components or groups of elements.
Subsequent separation (delamination and failure) of the interface zone results in an increasing displacement between the nodes (within the interface element) along the cohesive zone elements. Unless otherwise specified, the CZMESH command analyzes the configuration and geometry of the adjacent structural elements and provides the appropriate interface element.
The CZMESH operation copies any nodal temperatures you have defined on the split surface of the original mesh from the original nodes to the newly created coincident duplicate nodes. However, displacements, forces, and other boundary conditions are not copied.
If using CZMESH to generate interface elements (INTER202 and INTER205) in a VCCT-based crack-growth simulation, be aware that those elements do not support degenerate shapes. Examine the resulting mesh, therefore, to verify correct element connectivity around the crack tip.
The CZMESH command is valid for structural analyses only.
