How to set up a parametric distribution on a single machine

Requirements in the Supervisor

In Flux 2D and Flux 3D, the parametric distribution options (number of secondary Flux in parallel) may be set in the Supervisor's options or by clicking on the button Distribution Manager in the bottom right of the Supervisor. In Flux Skew module, this feature is available only for Physical and Mechanical set parameters.

In any case, the parametric distribution may be set as follows:

  • The Distribution Manager may be started in the Supervisor's options, in the Parallel Computing menu, in the section Distributed Computing and then click on the button Set local resources as shown below:


    Figure 1. The supervisor's options allow the user to set the parametric distribution.
  • An additional window Distribution Manager should appear and is asking to allow some resources (Number of secondary Flux in parallel) for the parametric distribution, click on Allow;
  • The Distribution Manager then asks for the Number of concurrent Flux as follows:


    Figure 2. The Distribution Manager asked for the Number of Concurrent Flux.

    This number is directly linked to the number of cores available on the machine, the numbers of varying parameters are automatically distributed over the number of concurrent Flux. The secondary Flux is automatically run in mono core mode but may be changed by using the slider Number of cores per concurrent Flux.

  • Finally, click on Use to complete the parametric distribution
  • The parametric distribution may also be started by clicking the button Distribution Manager in the bottom right of the Supervisor as shown below:

Define a parametrized scenario in Flux

Once the distribution has been set in the Supervisor, it may be employed as follow in a Flux scenario:
  • Check the box Parametric distribution in the selected Scenario.
    Note: All the varying parameters should be declared as Controlled parameters in the Control of parameters tab of the scenario as depicted below.
