In contrast to the feature (which only produces the mesh), the feature determines whether the geometry needs to be updated, refreshes the geometry if necessary, generates the mesh if necessary, and also writes the output data for any connected cells:
The feature is useful when you are investigating the impact of different settings on the mesh but you are not ready to export the mesh files.
The feature is useful if you make a connection in the Ansys Workbench Project Schematic from a Mesh cell to a system that requires a new type of output data (for example, if you make a connection from the Mesh cell to a Fluid Flow (CFX) or Fluid Flow (Fluent) analysis system). In such cases, the Mesh cell will go out-of-date. To bring the Mesh cell up-to-date, you can perform an on the Mesh cell from within the Project Schematic, or follow the procedure below from within the Meshing application.
To update the Mesh cell:
Select the Mesh object or any mesh control object.
Right-click to display the context menu.
Select in the menu.
Note: As an alternative to steps 2 and 3, you can click the button on the Mesh toolbar.
