This solves the crash instantly for many users:
Saving a project to a network drive, using unsupported characters in file names, or an unexpected power loss can corrupt .wbpj (Workbench project) or associated .mechdb , .files folders.
| Practice | Benefit | |----------|---------| | with incremental files (project_v1.wbpj, project_v2.wbpj) | Provides rollback points | | Enable auto-save (Tools > Options > Project Management > Auto-save interval) | Recovers from crashes | | Use .wbpz archives before major changes | Preserves complete state | | Keep drivers and ANSYS updates current | Fixes known crash bugs | | Monitor memory usage via Task Manager while working | Prevents out-of-memory crashes | | Work on local SSDs , not network drives | Avoids latency/corruption | | Close unused project components (e.g., suppress mesh before parameters update) | Reduces memory footprint | This solves the crash instantly for many users:
The crash occurs only when a specific plugin is loaded or used.
