Fast Solutions

  • FLAC2D features significant enhancements for modeling solution run times through multi-threading and algorithms to improve performance on modern hardware configurations. This includes for the mechanical, fluid, and thermal solutions; attach logic; and FISH scripting. The speed gains become greater for larger, more complicated meshes.
  • To take full advantage of multi-threaded FISH, a new LIST data type, SPLITTING syntax, and OPERATORS have been added, resulting in much faster execution of functions.
  • Implicit solvers for saturated-fluid flow and thermal calculations have been implemented for much faster analyses. Fast analytical temperature calculation for specified sources has also been implemented.
  • Maxwell Damping, an improved form of damping, is now available for zones, structures, and deformable links. With Maxwell damping, FLAC2D is a dynamics dynamo - making the analyses of large 2D site response and soil-structure interaction practical, while maintaining the high accuracy FLAC2D is known for.
