Bidirectional fluid-structure coupling error

Rolandbane · July 17, 2024, 04:45

Hello everyone, I have encountered an issue while using bidirectional fluid-structure coupling simulation. After updating the settings in the fluid module and transient module, the system coupling module fails to enter the settings for fluid-structure coupling. The specific error is:

(DP 0) The Setup component in System Coupling requires user input before it can be updated. Edit the System Coupling Setup cell, then right-click on any ? in the Outline tree, and select "Display Validation Failure" for more details.

How can I solve this problem?：困惑：

I solved the problem in a weird way by changing the initialization method from standard initialization to mixed initialization, but I still don't understand the reason behind it.
