FISH Rules and Usage

Information in this section covers the foundational aspects of the FISH language. The FISH Functions section in this FISH reference enumerates the functions built into the FISH language. The FISH functions available to query and manipulate FLAC3D model components (e.g., zones, zone faces, zone gridpoints, structural elements, etc.) are referenced in the FLAC3D Commands and FISH section. The contrast of built-in vs. FLAC3D-specific FISH functions can be seen on the FISH Index that lists all FISH functions by group.
