  I have simulated a two way FSI by ANSYS 2020R1. After doing all setups and execute the coupling system, I encounter the following warning
  
  Warnings were found during data model validation.                           |

  | Participant Fluid Flow (Fluent) (CouplingParticipant:Solution 1) has the    |
  
  |     ExecutionControl 'Option' set to 'ExternallyManaged'. System Coupling   |
  
  |     will not control the startup/shutdown behavior of this participant.     |
  
  | Participant Transient Structural (CouplingParticipant:Solution) has the     |
  
  |     ExecutionControl 'Option' set to 'ExternallyManaged'. System Coupling   |
  
  |     will not control the startup/shutdown behavior of this participant.     |

  but the simulation was continued without error. however, when I have interrupted the run, save the project and then click on the continue calculation, I have got the following error
  
  during the multiframe restart process the .rdb file was found but the .r file was not found
  
  any help will be appreciated.

  Have you provided time step in static structural and time step in fluent? In system coupling you also need to define the analysis time step.
  
  These two things are ok or not please confirm.

  thanks so much for your reply
  
  I have used the transient structure not static one.
  
  all settings are correct and with them in older version of ansys I did not get any warning or error.
