Hello

I'm a student studying welding engineering.

I'm going to use ANSYS to do fatigue analysis.

I have thermo-mechanical analysis data that previously analyzed the welding process with other software(Hexagon Simufact).

The extension of the data file is bdf, and I would like to bring the residual stress data stored inside the file to ANSYS for fatigue analysis.

I'd appreciate it if you could tell me how

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
