1 Simulate Inductive Sensors Using FEMM (Finite Element Method Magnetics)

When determining the resolution of an inductive sensing system, it can be especially helpful to simulate the response of the system before building the sensor. Finite Element Method Magnetics (FEMM) is open-source software that can simulate electromagnetic and electrostatic problems. This application note is a step-by-step guide for using FEMM to simulate inductive sensing solutions using LDC devices and estimate system resolution using the simulation results. This application note is applicable to the LDC3114, LDC161x, LDC131x, and LDC1101 devices.
