What's New in NCS 2.12?

NCS 2.12 brings another set of fresh new features to the framework. The focus was put on extending the range of use-cases covered by the standard framework, without any customization, as well as improving the capabilities of the core framework. To achieve this we:

  • Improved the default app template functionalities
  • Optimised the app template to minimise overhead around any NCS model’s prediction time
  • Introduced capabilities to read more input file formats from simulation and CAD
  • Extended morphing capabilities with a unique composable morpher, with the possibility to define structured morphing patterns

1. Improved Default Application UI

In this new version, the default NCS production application layout was improved to make the user experience smoother. In particular, the predicted outputs can easily be downloaded by the user in their preferred format, and boundary conditions can be frozen, or provided with better precision thanks to numerical input boxes.

2. Improved NCS Production Application Performance

Not only was the app’s frontend improved, but the app’s performance itself was enhanced. By introducing an optimized caching system, we restrict the amount of data sent between the frontend and the backend to the strict minimum. This allows to minimize the overhead around the model’s prediction time, and provide a truly real-time experience.

3. Support for more Native Simulation Formats

To make NCS compatible with an always larger range of use-cases, we implemented support for more simulation output formats in the MULTIMESH type. From 2.12, we now support the following additional formats using builtin readers:

  • Ansys Fluent .cas format
  • Ansys EnSight .case format
  • Unstructured CGNS format

4. Composable, Structured Deformations

NCS 2.12 introduces a new free-form parametrization framework to deform some template designs during shape optimization. This tool makes it possible to obtain much more freedom than possible before during design optimization. Some major strengths include:

  • Composable deformations: any set of successive deformations can be applied, allowing for infinite flexibility, while keeping control over the parameter space at each step
  • Structured deformations: deformations respect the underlying structure of the template design that is being deformed, like periodicity or symmetries
  • Constrained deformations: by choosing “anchor points” in the designs, it is easy to define regions that should not be affected by deformations

Periodicity allows deforming details locally, with a general impact on the whole design. Here, deforming the section of heat sink pins to maximise surface area.
