Time-dependent Magnetic Coils - limited to 1? #5

Closed DoviShamir closed 2 years ago

DoviShamir commented 2 years ago

Currently (excuse the pun) "A time-dependent magnet field can be created by a time-varying electric current running through a coil. Note that more than one time-dependent magnetic coil cannot be defined in the parameter file as this is not implemented yet"

Is there any development work being done on multiple time-dependent magnetic coils?

scopplestone commented 2 years ago

In your scenario, would you consider two or more coils running at a different or at the same frequency? I think this could be implemented quite easily depending on your case.

DoviShamir commented 2 years ago

In the scenario I envisage the coils (more than two) would be running at the same frequency but in different phases.

I have made the required changes to allow using an arbitrary number of time-dependent coils. It will only work when all these coils use the same frequency as different frequencies would have required making significant changes to the code, e.g., finding a common time span of multiple different periods or using multiple containers, one for each time-dependent coil. The next minor Release version 2.7.0 will contain the new features. The example in the picture will be located within the regression check directory under

2.7.0 is released including this feature, closing the issue!
