Me and my team-mates are working on a project and we now need to simulate a design we made.
We have a tube with a length of 10cm and a diameter of 2cm. At both ends of the tube, say x = -5cm and x = 5cm, a fixed magnet is placed. These magnets will be of same strength. We also place a magnet in the center of the tube (x=0). If the magnet is in the center of the tube the whole system will be in equilibrium. However, when we distort this equilibrium, The middle magnet will start resonating at a certain frequency. We now want to simulate this using Comsol.
We already have managed to create the three magnets in the tube using the mfnc physics. We now need to simulate the resonating middle magnet somehow. I'd be great if someone could give us some indication on how to do this. We think it needs to be done by using Moving mesh. I've read through some tutorials provided in the knowledge base but it didn't quite help me.
Help would be appreciated:)
