thank you for directing me to the right person.
Thank you for your reply. Could you please suggest how to simulate "3D electric field transient solver for this simulation with the trapezoidal excitations" Is there a tutorial or a course on Ansys Learning Hub that talks about this? Could you please share the resources and point me in the right direction?

How can I define user defined excitations like trapezoidal, square and arbitary waveforms of different shapeson 3D electric field transient solver?
