A collection of Fortran 2003, 90 and 77 routines, modules and programs for automatic simulation based global constrained optimisation. The initial application is for FE simulation of elasto-plastic buckling of steel rods aimed at tuning the hardening model. Unix shell scripts are used extensively. High concurrency is achieved with parallel multi-start global search and with parallel MPI FE. Powell's BOBYQA or LINCOA are used (not included in this package). Automatic mesh generation of 3D cylinders is provided + automatic boundary conditions, all via Fortran and shell scripting.

Features

  • Fortran
  • the Abaqus
  • Unix shell
  • hierarchical parallelisation
  • MPI

Project Samples

Circle mesh obtained by conformal mapping of a square Bucking of 20mm diameter rod in 1st mode Bucking of 20mm diameter rod in higher mode Initial mesh for buckling of a short rod with small inital perturbation based on the 1st eigenvector Deformed mesh for a short rod after buckling. Note high plastic strains near constrains single starting point optimisation workflow
