- Mapdl.czmesh(ecomps1='', ecomps2='', kcn='', kdir='', value='', cztol='', **kwargs)¶
Create and mesh an interface area composed of cohesive zone elements.
APDL Command: CZMESH
Component name or number for the group of plane or solid structural elements adjacent to the interface being meshed.
Component name or number for the opposing (from ecomps1) group of plane or solid structural elements adjacent to the interface being meshed.
Coordinate system number for the separation surface and normal direction. (if ecomps1 and ecomps2 not specified)
Direction (x, y, or z) normal to separation surface in the KCN coordinate system (if ecomps1 and ecomps2 not specified).
Coordinate value along the KDIR axis at which to locate the interface (if ecomps1 and ecomps2 not specified).
Optional absolute tolerance about VALUE (if ecomps1 and ecomps2 not specified). Allows nodes occurring slightly above or below the separation to be grouped properly. The following expression represents the default value:
CZMESH is used on a mesh with shared nodes at the interface.
If ecomps1 and ecomps2 are 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 will share nodes with each other and also with the interface elements. This one- element thick boundary of interface elements will split the body between the two components or groups of elements.
Subsequent separation (delamination and failure) of the interface zone will result 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.
The CZMESH command is valid for structural analyses only.
