I have been using Flux® since 2012, since I began with my MSc. research. I have been using it for just over two years.
I use Flux® mainly for modelling of machines, more specifically generators. I use it to create 2D FE models for both steady-state and transient analysis.
It has greatly benefitted my research. I am able to accurately model our experimental machines. In this way, I can work more efficiently through carefully planning laboratory experiments by first running simulations. Additionally, there is a freedom for designers when using Flux®, which is especially beneficial for research purposes.
I have recommended Flux® to my colleagues in the past and will do so with future colleagues as I have found that Flux software can solve complex problems and yet still maintain its user-friendliness.
