Infrastructures and Measurement Techniques

Model-based systems engineering (MBSE) is a methodology to represent a system in terms of digital models and connections between them. Especially for NB₃Sn and HTS magnet designs, where mechanical stresses are increasingly difficult to handle, MBSE can help set up multi-model simulations and automate the exchange of simulation results between simulation domains.  In addition, it provides a structure that can aid product life-cycle management of the magnet design. Working top-down and bottom-up, we extended our tools with the necessary interfaces to integrate them into the MBSE approach.

• Containerized ROXIE: An easy, reproducible way of installing and distributing ROXIE to any environment, including GUI access and REST API for interaction.
   
• Roxie-api: A Python Interface to facilitate scripted interaction with ROXIE: Input-file generation and modification, parsing of simulation results, and execution of ROXIE. Available on CERN GitLab and Pypi.
• Interface extension: Transformation of Iron meshes (gmsh, Hypermesh) to Roxie mesh format, Generation of step files for conductors and end spacers.
• MBSE-docker-environment: A test setup for the integrated environment for a magnet design. It is possible to set up a magnet design (system), different models (magnetic, geometry, mechanical, simulations), and their interaction. Integration of ROXIE and Ansys as tools, and functions to automatically load and resolve inter-model dependencies.
