  Hi everyone,
  I'm currently working on a two-way FSI simulation and have set the RMS convergence target to 1e-05. However, I encountered an error with the message: "Solution not converged at time 0.405 (load step 81 substep 1)."
  Could anyone offer suggestions on how to resolve this issue? Thanks!

  Hello Farah,
  Please check which participant failed. You can inspect the log files of each participant for this and adjust the settings accordingly to get the converged solution.
  From error, it appears that the MAPDL Solution fails to converge.
  You can find some best practices to improve the accuracy: I mproving the Accuracy of Transient Analyses (ansys.com)
  Hope this helps.
