Abstract In the framework of design studies for tokamak superconducting magnets a first step is usually required of pre-dimensioning that provides a rough magnets dimensioning, followed by detailed analyses. Such analyses aim at verifying that predefined design criteria are met in normal and in off-normal operation conditions, in order to ultimately progress step by step towards the most optimized configuration with respect to defined factors of merit of the tokamak. These studies involve several physics and thus several specific numerical codes modelling those physics. In order to handle these process analyses as efficiently and reliably as possible, the development of a multi-physic platform is underway at CEA. This platform, called OLYMPE, integrates different solvers under the supervision of a single actor for interfaces management. Furthermore, the availability of an integrated tool such as OLYMPE also aims at providing a possibility to easily run parametric studies in an automatic mode, to access to more efficient methods for confrontation with experimental data. In this paper, the structure of the platform is described, detailing the different codes and the coupling between the codes. The development status of these different codes included in OLYMPE workflow will also be exposed. Another part of the paper will present the application of the two most advanced OLYMPE modules (electromagnetic and thermal-thermohydraulic) on two projects. The first application is about the modelling of the experimental tests performed on the JT-60SA Toroidal Field coils tested in the Cold Test Facility. Parametric studies on some defined parameters are performed to fit the experimental data (e.g. impact on the thermal loads of the winding pack detachment from the casing, effect of pancakes friction factor variability…). The second application focuses on the CEA design proposal for EU-DEMO Toroidal Field (TF) magnets, where other parametric analyses will be provided.

OLYMPE，一个用于融合磁体设计的多物理平台：开发现状和首次应用

摘要 在托卡马克超导磁体设计研究的框架内，第一步通常需要预先确定尺寸，提供粗略的磁体尺寸，然后进行详细分析。此类分析旨在验证在正常和非正常操作条件下是否满足预定义的设计标准，以便最终逐步朝着关于托卡马克的定义的优点因素的最优化配置前进。这些研究涉及多种物理学，因此涉及对这些物理学建模的几个特定数值代码。为了尽可能高效和可靠地处理这些过程分析，CEA 正在进行多物理场平台的开发。这个名为 OLYMPE 的平台在单个参与者的监督下集成了不同的求解器，用于接口管理。此外，诸如 OLYMPE 之类的集成工具的可用性还旨在提供一种在自动模式下轻松运行参数研究的可能性，以访问更有效的方法来处理实验数据。在本文中，描述了平台的结构，详细说明了不同的代码以及代码之间的耦合。OLYMPE 工作流程中包含的这些不同代码的开发状态也将被曝光。论文的另一部分将介绍两个最先进的 OLYMPE 模块（电磁和热-热液压）在两个项目中的应用。第一个应用是关于在冷测试设施中测试的 JT-60SA 环形磁场线圈上进行的实验测试的建模。对一些定义的参数进行参数研究以拟合实验数据（例如对绕组包从套管分离的热负荷的影响，煎饼摩擦系数变化的影响……）。第二个应用程序侧重于 EU-DEMO 环形磁场 (TF) 磁体的 CEA 设计方案，其中将提供其他参数分析。
