The crash occurs when opening a specific project, but new projects work fine. Diagnostic file may show XML parsing error or unexpected end of file .

Introduction Few things are more frustrating than losing hours of simulation work to a sudden crash. For users of ANSYS Workbench, one particularly notorious error message stands out: "ansyswbu.exe encountered a problem. A diagnostic file has been written." The crash occurs when opening a specific project,

This error typically appears mid-simulation, during mesh generation, or even while simply opening a project. It forces an immediate shutdown of the Workbench user interface (WBU), leaving engineers scrambling to recover unsaved data. While the promise of a "diagnostic file" suggests a straightforward fix, the reality is that the root cause can range from insufficient RAM to corrupted project files, graphics driver conflicts, or licensing issues. For users of ANSYS Workbench, one particularly notorious

If you encounter this error repeatedly despite following the steps above, consider evaluating your workstation specifications against ANSYS’s hardware requirements, and ensure you are running a certified graphics driver configuration. Simulation stability begins with a stable foundation. Last updated: For ANSYS Workbench releases 2022 R1 through 2025 R1.
