block to-flac3d command

Syntax

block to-flac3d keyword

Primary keywords:

face-groups    filename    merge-join    zone-groups

Export 3DEC zones and joints to files for creating FLAC3D zones and interfaces. FLAC3D zones will be assigned group names and slots equal to block groups in 3DEC. In addition, if Merge-Join is set to \(true\) zones will also be assigned a group name equal to the block master ID in the slot smaster. Faces will be assigned group names related to the joint id (as a string) in slot ‘jset’. The actual face group name will be the joint set id appended by \(_n\) where \(n\) is an incrementing number required to separate faces that cross other joints. The interface name will be the same as the host face name prepended by \(i\). Interfaces will be assigned group names simply equal to the joint set id prepeneded by \(i\). This makes it easy to assign properties to interfaces forming different joint sets by using the group range.

face-groups b

Set b to \(true\) or \(on\) to export user-defined face group names (i.e. other than the joint set ids). By default face group names are not exported.

filename s keyword

Specify the name of the output files. Two files will be created: a grid file with a .f3grid extension and a .dat file that calls the grid file.

binary b

By default, the grid file will be output in binary format. Set b to \(false\) or \(off\) to output in ASCII format.

merge-join b

By defaut, joined 3DEC blocks will have their gridpoints merged when imorted to FLAC3D. Set b to \(false\) or \(off\) to prevent this.

zone-groups b

Set b to \(true\) or \(on\) to export user-defined zone group names (i.e other than the block groups). By default zone group names are not exported.
