Performing the Calculation
When you have entered (and saved) all the necessary data, you can start the calculation. To do this,
- choose the menu item "Run | Run Calculation" to start the calculation for the current case, or
- choose the menu item "Run | Run all Calculations" to start the calculation for all the cases in the current project in succession, or
- choose the menu item "Run | Run Calculation with Film" to open the film dialog and click on the 'Start' button.
In the former two cases the screen just shows a progress bar so that you can estimate computing time; in the latter case, WUFI displays the calculated profiles at each time step, so that you can watch a sort of film showing the processes in the component. This film display is somewhat slower, of course, so that lengthy calculations should be done without film; on the other hand, you can immediately see what is happening.
During the calculation, WUFI wanders from the specified initial state through the evolution of the temperature and moisture fields, proceeding in discrete time steps, reading the changing boundary conditions from the climate file and writing the data of each step to a temporary result file. A progress bar allows you to estimate the remaining time needed for the calculation.
The calculation can be aborted at any time by a click on the stop button. The results accumulated so far are not lost and can be analysed.
If you have run the calculation with film, you can "Close" the film screen
after the calculation has ended.
After the calculation, a window "Status of Last Calculation" pops up, showing you a short summary of the calculation results. This window also contains some information that you should check to make sure that no serious convergence failure has occurred.
Important: If you want to keep the results, you must now write them to the project file by simply saving the project file again (make sure the options are set to save both input data and results in the project file).
Extensive calculations (such as parametric studies) can also be processed automatically as batch jobs.
