LS-OPT    (Chinese)                     AVI Library 71a 

Multi Forging
  
  
LS-OPT allows the user to structure the design process, explore the design space and compute optimal designs according to specified constraints and objectives. The program is also highly suited to the solution of system identification problems.

LS-OPT graphically interfaces with LS-DYNA and provides an environment to specify optimization input, monitor and control parallel simulations and post-process optimization data as well as viewing multiple designs using LS-PrePost.

LS-OPT contains the following features:
  • A command language forms the basis for the description of the optimization formulation and process.
  • A preprocessor can be incorporated into the design cycle.
  • A comprehensive LS-DYNA interface allows access to the ASCII binary databases.   Minima, maxima and averages can be requested.  Response filtering can be used.
  • Special metal-forming criteria such as FLD have been developed.
  • Simulations can be run concurrently.
  • LS-OPT allows multi-case and multi-solver designs to be analyzed.
  • A successive approximation procedure allows refinement of the solution and convergence to an optimum
LS-OPT and LS-PrePost are delivered with LS-DYNA
