Topology Optimization

LS-TaSC is a tool for the topology optimization of non-linear problems involving dynamic loads and contact conditions. It can be used to find a concept design for most structures analyzed using LS-DYNA.




General capabilities

  • Solid design using first-order hexahedrons and tetrahedral elements
  • Shell design using first-order quadrilateral and triangular elements
  • Global constraints
  • Multiple load cases
  • Tight integration with LS-DYNA
  • Large models with millions of elements

Geometry definitions

  • Multiple parts
  • Symmetry
  • Extrusions
  • Casting, one sided
  • Casting, two sided


  • Design histories
  • LS-PrePost plots of the geometry evolution and the final design
