I am using the Electromagnetic Desktop trying to measure the eddy currents in induced in an aluminum tube after the current passing through a nearby wire shuts off. I have found that currents in the Eddy Current solution type cannot depend on time, and have been working in the Transient solution type.
My question is: how can I apply a direct current that take a value at one point, and then a different value at another? A step function that passes a constant current for a certain time, and then no current past that time would be perfect.
I am having trouble finding a way to integrate this into my model, and was hoping somebody could point me in the right direction.
