ProTOp

A standalone topology optimization software that takes as input FNF and INP files, generated by PTC® Creo®, Simulia® Abaqus and SolidWorks® Simulation, respectively.

ProTOpCI

A standalone topology optimization software for PTC® Creo® users. Only FNF files generated by PTC® Creo® are accepted as input.

Features

  • Based on custom finite elements, developed in-house especially for topology optimization
  • FEA - highly parallelized code, high performance sparse solver
  • Optimizer - a hybrid evolutionary/level-set optimizer, highly parallelized code
  • Shell (envelope) and lattice structure generation from solid parts
  • Semi-contact and semi-plastic finite elements
  • Easy modeling of pin joints, bolt/rivet fastening, and similar contact situations
  • Simple and easy to use user interface; fully interactive optimization process

Capabilities

  • Structure: statically loaded, linearly elastic isotropic material
  • Objectives: minimum strain energy; maximum lowest eigenfrequency
  • Targeting: volume part, stress, displacement
  • Technological constraints: YES
  • Multiple load cases: YES
  • Smoothing and simplification tools for resulting surface mesh: YES

Hardware recommendations

  • CPU: A good entry is a 4-core i7 or comparable CPU. Note that 6 or 8 cores (e.g., 2 Xeons) are significantly better, but there is not much improvement when going beyond 12 cores.
  • RAM: A good entry is 16 GB, but for more serious work 32 GB is actually the minimum.
  • Drive: In cases of RAM shortage, ProTop/ProTOpCI will switch to partial out-of-RAM (disk) storage; in this case a dedicated (work) SSD on SATA III interface is recommended.
