双向流固耦合报错提示equested ChartableData->GetRootLeve怎么解决？ 20
浏览：1021
(DP 0) System coupling run completed with errors. Fluid Flow (Fluent) (Solution) reported: Exception encountered when the coupling service requested ChartableData->GetRootLevelName: Communication socket unexpectedly disconnected. Please do not save the project if you would like to recover to the last saved state. 我用ansys做双向流固耦合求解时出现这种问题什么原因了，有人知道吗
