I am trying to use the magnetostriction physics in COMSOL5.5 to simulate the excitation process of magnetostrictive displacement sensor.I hope the pulse current can excite torsional waves in the waveguide wire(this is made of magnetostrictive materials). The model contains a waveguide wire ,a ring magnet and air domain, and then a axial rectangular pulse(duration of pulse is 5us) is introduced in the wire. I've seen the official model about nonlinear magnetostrictive transducer.I've tried many times but the result does not converge. Has anyone else run into a similar problem? Are there any special setup skills in this model?

Thanks in advance!
