When beta features are enabled, you can have access to the Fault-tolerant Meshing guided workflow as a Workflow Type from the Properties window for the Meshing cell in the Fluent (with Fluent Meshing) component system.

Note that when the Create New option is selected, the Watertight Geometry workflow is assumed and an Import Geometry task is added to the new workflow. Alternatively, if you want to start with the Fault-tolerant Meshing workflow, you can delete this task and, using the Insert New menu option, you can add your own Import CAD and Part Management task. The CAD File and Display Units properties for this task will be directly valuated based on the Geometry path and Units provided by the Geometry component in the Workbench.
