FISH Scripting in FLAC

FISH is a scripting language embedded within FLAC that enables the user to define new variables and functions.
These functions may be used to extend FLAC’s usefulness or add user defined features (e.g., servo-control boundaries may be applied to a numerical test, unusual property distributions specified, and parameter studies automated).
Built-in text editor and FISH management pane
Integer, floating-point, and string data types that are automatically assigned and reassigned based on value
Control statements include CASE, IF-ELSE-ENDIF, EXIT, LOOP, LOOP WHILE, SECTION, and COMMAND
Built-in error handling
Use FISHCALL to access information at any point during the solution cycle (e.g., before any structure calculations or after the motion calculations) for each solution cycle or step
Built-in general scalar variables and intrinsic logic, mathematic, text, and parsing functions
Access FLAC solution variables, zone, and gridpoint variables (including zone strains and strain rates), and constitutive model variables
Access data tables, arrays, ASCII/binary data, I/O routines, data structures, and memory
Access socket I/O routines to exchange data between two or more Itasca software (FLAC or PFC2D) running as separate processes
FISH line statements can now contain up to 200 characters
Includes FISH Library function that can automatically vary the slope angle iteratively to reach a given factor of safety
