Dear all
I am doing two way fsi problem. during my CFX pre setup I found this type of error.Please rectify the problem "In Analysis 'Flow Analysis 1' - Analysis Type: The specified Mechanical Input File 'ds.dat' can not be found or does not contain any valid interfaces. Specify an input file with valid interfaces, update the file location if it has moved or set the External Solver Coupling option to "ANSYS MultiField via Prep7"." Regards Govind |

Your solid model is either
1) missing, or 2) does not contain any FSI interfaces. |

CFX-Pre sometimes gives this error for no apparent reason. Assuming the ds.dat file is there and it contain an interface, then delete the link between the two Setup cells in Workbench and re-create it.

You should reset the CFX-solver.
