最近建立一个二维电磁场仿真模型:线圈和铜盘,线圈电流由外部电路导入。预想情况:线圈通电,在铜盘上感应出涡流,相互作用产生电磁斥力,推动线圈运动(线圈在运动区域内,铜盘在运动区域外)。结果每次仿真都会出现如下错误提示。Time step at 0.000192 sec completed, process solver2d error: Internal Solver Error: 'Could not find the face: for translation motion and non-cylindrical rotation, the moving part must have a big object which contains all other objects, please check the model setup!'.
