Issue of Flux coupled with Activate

Hello,

These days, I work with Flux coupled with Activate for simulation of contactor dynamic behavior. The contactor has 2 coils, 3 switches. The 3 switch is controlled by activate. While the current of the 2 coils are used as sensor input for Activate.

 

But when I start the simulation, at beginning the current in the coil seems reasonable. But after 5ms, or like this, the current and voltage on the coil starts to become very strange, and non-meaning, just noisy points, I don’t under stand why. I think, the activate only control the switch and do some control, very simple, the Flux finish FEM calculation.

When I work with Flux alone, same calculation performed, no noisy points. For solver I use same as tutorial showed for activate and Flux coupling simulation.

 

I hope I can get some help for this topic.

Thanks.

    Hello,

    I think we need your Flux and Activate files in order to better understand what is going on.

    Note: it seems this request has also been sent to direct support. Please send us your project, or a similar basic project where you can reproduce the case.

    regards
