Refreshing system components reads in all modified upstream data but does not necessarily regenerate the outputs of the component itself. For example, if the geometry changed, placing the Mesh cell in a Refresh Required state, refreshing the Mesh cell updates the geometry without generating a new mesh (which could potentially be a lengthy operation).
To refresh system components:
To refresh all cells in the project that are in a Refresh Required state, from the menu bar select > , or on the Project tab toolbar click .
To refresh a system, right-click the system header and select from the context menu.
To refresh a cell, right-click the cell and select from the context menu.
