Ansys Electronics Desktop (AEDT) provides a common user interface for multiple products, where each product focuses on a specific kind of physics. Ansys HFSS offers two different approaches: (1) HFSS fully arbitrary 3D (FA3D), which is also known as MCAD, and (2) HFSS 3D layout. HFSS 3D layout can be extensively used for simulations with layers, nets, components and padstacks. It also contains multiple solver types. HFSS 3D layout structures geometry in terms of layers that are common in electronic computer-aided design (ECAD), including printed circuit board (PCB) layout and RF/microwave circuits. The 3D meshing and FEM simulation in HFSS 3D layout are the same as in HFSS fully arbitrary 3D geometry (MCAD) simulation. This course focuses mainly on the basics of HFSS 3D layout and emphasizes its key features and capabilities.
