Select ANSYS Input under File Type and choose the surface(s) for which you want to write data in the Surfaces list. If no surfaces are selected, the entire domain is exported.
When the Energy Equation is enabled under the Define/Models/Energy... menu option, you can choose the loads to be written based on the kind of finite element analysis you intend to undertake. By selecting Structural in the Analysis list, you can select the following Structural Loads: Force, Pressure, and Temperature. By selecting Thermal in the Analysis list, you can select the following Thermal Loads: Temperature, Heat Flux, and Heat Trans Coeff. Note the following limitations with these loads:
You also have the option of exporting data at specified intervals during the calculation through the Solver/Execute Commands... menu option. See Section 4.12.18 for the complete details.
Click the Write... button to save the file, using the Select File dialog box. FLUENT exports an input file that contains ANSYS finite element information including nodes, elements, and loads that can be used to do finite element analysis in ANSYS with minimal effort. The file format is written in .cdb format. The export of ANSYS Input files is in ASCII format and thus is available on all platforms.
