interf_topol : topology file for Interface Elements
- Brief description : defines the type, fault index, material index and the nodal connections for each interface element.
- Additional information : the type of interface element to be used depends on the type of 3D element in the continuous mesh
(see Interface Element section for details).
- File type : formatted ASCII. In Fortran language, the formats for the header and a row of the
bulk are
'(i10,110a)'
and '(12i10)'
, respectively.
- Index of the file path in ATLAS.fnames : 16
- Parameters to be set :
