Simcenter 3D Optimization

Automating the product performance process 

Simcenter 3D optimization solutions streamline and automate that process by using sophisticated algorithms to search the entire design space and find the right combination of parameters that will yield optimal design and performance. To help the program know what you mean by optimal, you specify design and performance objectives for characteristics such asminimum weight, shape constraints and minimum stress or strain. Design parameters that you can vary include geometric, material and connectivity properties.

Reduce design risk and accelerate innovation 

By better understanding the complex relationships among design parameters and how changes affect them, you can gather insight into product performance risk and accelerate innovation by determining feasible designs that satisfy all requirements.


Shorten time-to-market with confidence

Analyze your product performance deviations from specifications in a variety of operating conditions, and shorten time-to-market by automating thousands of simulations that would otherwise have to be performed manually.

Simcenter Nastran Topology Optimization

Simcenter Nastran Topology Optimization software offers the capability to optimize many different criteria in support of generative engineering. The solution enables the user to optimize the topology of regions defined as solids or shells and offers the capability to predict solid and lattice zones.

Key features

  • Many methods are available to build the finite element (FE) model: orphan mesh, single computer-aided design (CAD) part and single finite element method (FEM), CAD assembly and single FEM or AFEM
  • The design areas can be constructed using 2D shell or 3D solid elements and there can be multiple design areas with different materials representing different parts in an assembly, or homogenized meta-materials (lattices, varying density printed materials, etc.)
  • Within a single topology optimization, the user can have any mix of analysis subcases selected from linear statics, normal modes, buckling analysis, direct and modal frequency
  • There are hundreds of responses available for the objective and constraints
  • Synthetic variables and responses can be created and combined with other responses in equations as responses for the objective and constraints

Simcenter 3D Design Space Exploration

Simcenter 3D Design Space Exploration brings the power of parametric design space exploration to the desk of the user with low cost of adoption. It helps companies to move beyond standard use of simulation for validation, troubleshooting and basic prediction by automatically exploring broader design spaces to more rapidly discover much better designs.

The user can leverage smooth process automation, which simplifies the virtual prototype build process to exploit the distributed execution that accelerates vir-tual prototype testing. This enables the user to access efficient design search capabilities without the need for simplifying models. Additionally, the user has access to a complete insight and discovery interface that is a central part of virtual product development rather than an afterthought.
