You can perform one-way FSI operations manually (by exporting CDB files from Mechanical APDL, importing the surface in CFD-Post, and exporting the SFE commands).
To create an Ansys load file using CFD-Post to transfer FSI data:
Load the fluids results file, from which you want to transfer results, into CFD-Post
Select File > Import > Import Mechanical CDB Surface. The Import Ansys CDB Surface dialog box appears.
In the Import Mechanical CDB Surface dialog box, either:
Select the CDB file that specifies the surface mesh of the solid object to which to transfer data. Also select the Associated Boundary for the surface to map onto, and make other selections as appropriate.
Select the XML document that provides all transfer information. Click , and the surface data is loaded.
Select File > Export > Export Mechanical Load File. The Export Mechanical Load File dialog box appears.
In the Export Mechanical Load File dialog box, select a filename to which to save the data. For the Location parameter value, select the imported Ansys mesh object. Under File Format select Ansys Load Commands (FSE or D). (Alternatively, you can select WB Simulation Input (XML) to get XML output.) Also select the appropriate data to export: Normal Stress Vector, Tangential Stress Vector, Stress Vector, Heat Transfer Coefficient, Heat Flux, or Temperature. Click , and the data file is created.
The one-way FSI data transfer described above is performed automatically when using the FSI: Fluid Flow (CFX) > Static Structural custom system in Ansys Workbench. For details, see the FSI: Fluid Flow (Ansys CFX) > Static Structural in the Workbench User's Guide section in the Ansys documentation.
