FISH SCRIPTING

• 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
