Hello Kang,

Yes, it is possible to bulk data file(*.bdf) into Ansys for your fatigue analysis. Please refer to the below steps:

• In the BDF (Bulk Data File) format you mentioned, please ensure the data includes each node’s stress tensor components (Sxx, Syy, Szz, Sxy, Sxz, Syz) before you export it.
• In ANSYS Workbench, create a new Static Structural analysis system.
• Import the geometry of your welded part into the Static Structural system.
• Right-click on the Geometry cell and select “Import Geometry”. Browse to the BDF file exported from Simufact and import it.
• ANSYS will read the residual stress data from the BDF file and map it onto the imported geometry. The stress tensor components will be available as solution data.
• This solution data can be mapped to your fatigue analysis module
