Other Solver File Features

"Cleaning" Solver Files

Cleaning solver files after they've been updated to the MASTER project is beneficial for saving and storing the data as for large projects gigabytes of replicated data can be removed to free up space on your machine.


Each solver file contains general data relating to the MASTER project file such as information regarding the geometry, leak locations, defined gas properties, etc. This data is needed to calculate the results however once simulations have complete this general project data is no longer needed as it is contained in the MASTER file. “Cleaning” the data files deletes this repeated data in each solver file.

It is important to first ensure that all the solver files have been synced and updated with the MASTER file before cleaning them. To clean solver files r ight-click the Data Files option in the Project Items Tab and select Clean All. 


Note that the opposite of cleaning solver files would be to Copy Project Data to All described above, however it is recommended to always make backups before performing this function.



Consolidate Solver Files

Some projects can have upwards of 50 or more solver files which may become difficult to transfer or manage. Additionally, the scope of a project may change so not all completed simulations are needed for the project. For situations such as these, the consolidate feature can be used. The features combines the completed simulation data into a smaller number of solver files, or the main .ifx project file itself.


To use this feature, right-click on Data Files in the Project Items Tab and select Consolidate, shown below. A small window, shown below, will appear. Here you can select to consolidate the solver files into a smaller number of files. A field is available to specify the number of files to make and the estimated number of simulations per each file. Click the Consolidate button to start the process.

The consolidate feature will create new data files and automatically link them to the main in:Flux project. It will not delete the original existing data files. Once the consolidation process is complete you may choose to delete the original files.


Alternatively, you may set the method to Into Main Project File. This will bring all the completed simulation data into the main .ifx file. Note this will significantly increase the size of the .ifx file. Using this method, you will be prompted to delete the older .ifxs solver files upon consolidation.

Touch Up Solver Files

A debugging feature in in:Flux which forces all solver files to an out of date state - thus forcing them to need to be updated. This may be useful if in:Flux believes it has updated all project data when in reality it has not. To use this feature, right-click Data Files in the Project Items Tab  and select Touch All.



Using ifx:Solve to create more Distributed Solver Files

When running large projects and deploying solver files to multiple machines, some will complete faster than others. This may be because the processing power of one machine is greater than the other or some function behind the scenes in windows was using more computing power.  If this is the case and one file still has several cases to complete after other solvers have fully finished, then you may want to split a solver file a second time to distribute the computational work load and finish computing the project. 


As an example the Tutorial 13 -00.ifxs file will be used:

  1. Stop the simulations in ifx:Solve for the file you want to split

  2. Save the file

  3. Click the Create Distributed Solver Files button, shown below. You will be prompted in how many files should be created. Enter a value and click Create. New files will now exist in the directory with a naming strategy:

    1. Tutorial 13 -00 -00.ifxs

    2. Tutorial 13 -00 -01.ifxs, etc...

  4. Now run these newly created solver files in new ifx:Solve instances as before.

  5. When complete, the MASTER file will need to have these new files added. To do this, right click the Data Files text and select Add Data Files.

Reset Crashed Simulations within ifx:Solve

In the rare case that one of cases crash while being calculated in ifx:Solve you can reset it by going to the Completed tab and right-clicking in the window. A context menu will appear, select Reset All Crashed (shown below).


Note - the crashed cases may appear in the scheduled tab, complete tab or unscheduled tab, performing the steps mentioned will reset crashed cases regardless of their location within the tabs.


Click Yes on the next screen to confirm resetting crashed cases and after some processing those cases will be sent back to the Scheduled tab.

This completes Tutorial 13, providing a description of the uses for Distributed Solver Files (*.ifxs) with in:Flux and ifx:Solve.
