  I need guidance on setting up a 2D analysis of an LVDT in maxwell. I have my geometry modelled with materials, but I cannot figure out the correct way to setup the coils/windings (apply an AC excitation to the primary coil, and read the induced voltage from the secondary coils during a moving core sweep.) Does the AC excitation need to be a function?

  Hi,
  AC excitation can be defined using a function, a data table, or a circuit. demonstrates how to set up excitation using each of these methods. The same approach can be applied in 2D simulations as well. This workshop is part of the Ansys Maxwell Getting Started - Ansys Learning Hub. Additionally, I recommend reviewing the lecture Maxw_GS_2023R2_EN_LE4.1_MagneticTransientSolver, which provides an overview of the different excitation types supported by this solver
  Furthermore, to plot the Induce Voltage, ones the model is solved, go to Maxwell 2D / Results / Create Transient Report/ Rectangular plot –> Category = Winding / Quantity = Induce Voltage
