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

Postprocessing
