Improved Plotting and Movies
  • Plots can be set to refresh automatically or manually during model cycling.
  • Up to 20 movie frame sets can be created during cycling and saved to different folders.
New Commands and Keywords
  • Added SET digits command to specify decimal digits for outputs from PRINT command.
  • Added SET memory to specify RAM memory allocation within FLAC.

  • Added badgeomrat FISH intrinsic for minimum aspect ratio over the whole grid.
  • Increased filename length limit to '200' if '@'symbol is used before a filename.
  • Added fish.xml to the FISH folder.
Improved Structural Elements
  • Added FISH option in the GUI for structural node load.
  • Added range for grids when structure nodes are rigidly connected to grid points.
Improved Automatic Rezoning
