The system thermal–hydraulic code TRAC/RELAP Advanced Computational Engine (TRACE) and the sub-channel code SubChanFlow (SCF) have been coupled together based on the Interface for Code Coupling (ICoCo) and the SALOME platform. It is a server-client system where TRACE and SCF are computational engines, ICoCo transfers the coupling data, and SALOME supervises the two clients’ synchronization. TRACE and SCF run serially. The coupled code adopts the domain-overlapping (assisted by a Dynamic Implicit Additional Source (DIAS) method) and the Operator Split (OS) explicit coupling approaches. The MEDCoupling library manages the field mapping between different meshes of TRACE and SCF. The YACS module in SALOME provides developers with useful tools that can implement numerical codes in SALOME. It provides users with Graphic User Interfaces (GUI) that can construct and execute the coupling simulations as well. Users can conveniently build/optimize/execute the coupling schemes in SALOME. The coupled code has been verified with an AP1000 feedwater-temperature-drop transient.

系统热工代码TRAC / RELAP高级计算引擎（TRACE）和子通道代码SubChanFlow（SCF）已基于代码耦合接口（ICoCo）和SALOME平台耦合在一起。它是一个服务器-客户端系统，其中TRACE和SCF是计算引擎，ICoCo传输耦合数据，而SALOME监督两个客户端的同步。TRACE和SCF串行运行。耦合代码采用域重叠（由动态隐式附加源（DIAS）方法辅助）和运算符拆分（OS）显式耦合方法。MEDCoupling库管理TRACE和SCF的不同网格之间的字段映射。SALOME中的YACS模块为开发人员提供了可以在SALOME中实现数字代码的有用工具。它为用户提供了图形用户界面（GUI），它也可以构建和执行耦合仿真。用户可以方便地在SALOME中构建/优化/执行耦合方案。耦合代码已通过AP1000给水温度下降瞬变进行验证。
