ESI Group Releases SYSTUS 2017 with Topology Optimization

ESI Group releases updated simulation software that includes fracture mechanics analysis and topology optimization.

Virtual prototyping software company ESI Group has announced the new release of its latest simulation package, SYSTUS 2017, which is aimed largely at the nuclear power sector.

The latest iteration of the package boasts several new features for thermomechanical design engineers, including a new Differential Method for solving.

In addition to the new solver innovations, ESI is drawing attention to its new fracture analysis capabilities, which make use of the X-FEM method.

The new fracture analysis allows users to perform both brittle and ductile analyses on models using X-FEM (eXtended Finite Elements Method),which reduces workload by allowing the analysis of defects without the need to model the cracks explicitly. The X-FEM method permits defects to be modeled and analyzed using the level-set method. Additionally, X-FEM takes into account the plasticity of bodies and permits the meshing of models with quadratic elements.

In addition to the improvements under the hood, SYSTUS 2017 has front-end improvements, including a refined GUI and simplified commands.

And what would a software release in 2017 be without some form of design optimization? SYSTUS 2017 is no different in that regard and has included the ability to perform topology optimization on shapes—specifically targeting the aeronautical and automotive industry (because those industries both love a bit of lightweighting). Again, the topology optimization in SYSTUS 2017 is based on level-set technology.
