Workbench integrates multiple systems (for example, FENSAP-ICE) and native applications into a single, seamless project flow, where individual cells can obtain data from and provide data to other cells. Workbench provides visual indications of a cell’s state via icons on the right side of each cell. Brief descriptions of each possible state are provided below. For more information about cell states, see Understanding Cell States.
- Unfulfilled
Indicates that required upstream data does not exist. For example, when you first create a new Fluid Flow (Icing – FENSAP) analysis system, all cells downstream of the Setup Flow cell appear as Unfulfilled because you have not yet specified a grid for the system.
- Refresh Required
Indicates that upstream data has changed since the last refresh or update. For example, after you assign a grid to the Setup Flow cell in your new Fluid Flow (Icing – FENSAP) analysis system and update the cell, the Solution Flow cell appears as Refresh Required since the grid and input settings has not yet been passed from the Setup Flow cell to the Solution Flow cell.
- Attention Required
Indicates that the current upstream data has been passed to the cell, however, you must take some action to proceed. For example, after you launch FENSAP from the Setup Flow cell in a Fluid Flow (Icing - FENSAP) analysis system that has a valid mesh, the Setup Flow cell appears as Attention Required because additional data must be entered in FENSAP before you can calculate a solution.
- Update Required
Indicates that local data has changed and the output of the cell must be regenerated. For example, when you change a setting, for example, a boundary condition inside the Setup Flow cell of a Fluid Flow (Icing - FENSAP) analysis system that has a valid mesh, the Setup Flow cell appears as Update Required because the Setup Flow cell has all the data it needs to generate a FENSAP config file, but the FENSAP config file has not yet been generated.
- Up-To-Date
Indicates that an update has been performed on the cell and no failures have occurred (or an interactive calculation has been completed successfully). For example, after FENSAP finishes completing the calculations, the Solution Flow cell appears as Up-to-Date.
- Interrupted, Update Required
Indicates that you have interrupted an update (or canceled an interactive calculation that is in progress). For example, if you select the Cancel button in FENSAP while it is iterating, FENSAP completes the current iteration and then the Solution Flow cell appears as Interrupted, Update Required.
- Input Changes Pending
Indicates that the cell is locally up-to-date, but may change when next updated as a result of changes/modifications made to upstream cells. For example, if you change the Mesh in an Up-to-Date Fluid Flow (Icing - FENSAP) analysis system, the Setup Flow cell appears as Refresh Required, and the Solution Flow and other downstream cells appear as Input Changes Pending.
- Pending
Indicates that a batch or asynchronous solution is in progress. When a cell enters the Pending state, you can interact with the project to exit Workbench or work with other parts of the project. If you make changes to the project that are upstream of the updating cell, then the cell will not be in an up-to-date state when the solution completes.
If a particular action fails, Workbench provides a visual indication as well. Brief descriptions of the failure states are described below.
- Refresh Failed, Refresh Required
Indicates that the last attempt to refresh cell input data failed, and so the cell must be refreshed.
- Update Failed, Update Required
Indicates that the last attempt to update the cell and calculate output data failed, and so the cell must be updated.
- Update Failed, Attention Required
Indicates that the last attempt to update the cell and calculate output data failed, and so the cell requires attention.
If an action results in a failure state, you can view any related error message in the Messages pane by clicking the Show Messages button on the lower right portion of Workbench.
