Recently, I set up such a fluid-structure two-way coupling analysis, when I pause the simulation and change the step size and the maximum iterations in the system coupling, and then simulate again, I found that the displacement of the monitor point in the transient structure would deviate from the original trend. The fluent will report an error "Deleting Client...done Shutting down Server...done Error: Rpc Communication failure during SCAnalysis:GetCouplingDefinitionMethod call at cortexmpc,c:423", followed by a flashback, and finally the simulation stops unexpectedly. I tried not to change any settings, just paused the simulation process, and when I hit the Continue Calculation button in the System Coupling, I also got an error and could not continue.
