Multiphysics analysis, involving the coupled phenomena of various physics fields, such as electro-mechanical, thermofluidic, thermoelectric, and thermo-hygric phenomena, plays a critical role in advancing technology engineering disciplines. Conventional numerical algorithms are generally time-consuming resource-demanding. Thanks to rapid development deep learning (DL), data-driven, physics-informed, operator methods have been proposed accelerate calculation process. However, existing DL methods, encompassing convolutional neural network (CNN) graph (GNN) based approaches, exhibit limitations effectively handling irregular regions addressing challenges posed by multiphysics tasks. To tackle these problems, we propose framework on GNN with solver. In solving process framework, is generated according given region, then coupled-field (GCFSN) adopted. We conducted three experiments using GCFSN solve mean relative error about 5%. The experimental results verified superior performance generalization ability method thermal-coupled problems an region.
