workbench做fluent双向流固耦合出错

在做一个workbench和fluent的双向流固耦合，可是总出错，最多的一个问题是One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.想问问大神们知道这个错误如何改吗，是我的接触设置错了还是，约束，运动副加错？
