The distribution of computations is available in FluxMotor.
Overview
The parametric distribution of the FluxMotor solver, “Flux”, is now possible on a single machine. Distributed computing allows the user to save computation time.
For example, a test “Scalar Maps” may be automatically distributed if the Flux distribution mode is enabled. In this case, several Flux projects will run at the same time to solve all the required test configurations.
The main parameter of a distributed computation is the “Maximum number of cores used in distribution mode” (i.e., the number of running Flux in parallel).
How to set up a parametric distribution on a single machine?

1 | Button to enable the Flux solver distribution mode |
2 | Button to select the maximum number of cores used by the distribution |
3 | Button to set the allocated memory (The static allocated memory is recommended) |
Principles
The “Flux distribution mode” allows the user to save computation time by parallelizing the Finite Element (FE) solving of a test.
Indeed, FE solving is done by parallelizing several independent configurations of a FE problem (such as the value of the stator current) instead of running them sequentially.

Flux distribution mode - Flux process operating principle |
When the Flux distribution mode is activated, FluxMotor automatically uses it and manages the number of cores used to reduce, as far as possible, the computation time.
