Creating Distributed Solver Files

Continuing from the last section, simulations will have been added to the project but have not yet started calculating. At this point a Distributed Solver File can be made. If your project has already started calculating simulations, press the Stop button on the tool bar ( ) before continuing.


A "Distributed Solver File” takes the simulations that are currently in the scheduler and splits them up into separate .ifx files. These files can then be copied to other machines and loaded into a second instance/window of in:Flux or the ifx:Solve software to run simultaneously.


Download and open the Tutorial 13 in:Flux file used for this tutorial.


Follow the below steps to create four Distributed Solver Files for the project:

  1. Save the project to a location where you wish to store all the solver files. If this is not done, the solver files will be created in the directory in which you opened the file from.

  2. From the File Menu select Create Distributed Solver Files... as shown in the figure below.


    Tutorial 13 - Figure 3 - Indication of where to create distributed solver files


  3. In the window that appears increase the Number of Files to 6. This will show that each of the six files will contain 107 simulations. in:Flux does not limit the number of files created in this way.

  4. Click Create Files


    Tutorial 13 - Figure 4 -Distributed Solver File creation window


Six files will then be created and saved to the directory where the current in:Flux project was saved. They will be named in the following manner:

  • Tutorial 13 -00.ifxs

  • Tutorial 13 -01.ifxs

  • Tutorial 13 -02.ifxs

  • Tutorial 13 -03.ifxs

  • Tutorial 13 -04.ifxs

  • Tutorial 13 -05.ifxs 



Each data file will now be referenced in the Project Items Tab under the Data Files section for the current in:Flux project which created them, this will be the MASTER file for the project.

The solver files can each be opened in in:Flux. However, no 3D model will appear and only a portion of the simulations will be present (depending on the number of solver files made). It is important to keep all these files with project file that created them (the MASTER file) when setting up the project and after calculations have completed.



Continue to the next sections to go through what can be done with each of the solver files.
