Simulation software: HFSS 13
Thanks
Maxwell 13 - is the leading software for modeling electromagnetic fields used for the design and study of two-and three-dimensional models, such as motors, sensors, transformers and other electrical and electromechanical devices for various applications. Maxwell ? is based on the finite element method (Finite Element Method - FEM) and accurately calculates the static, harmonic electromagnetic and electrical fields, as well as transients in field problems.
As far as I know neither is including (or the same as) HFSS.
HFSS and Maxwell were/are softwares by Ansoft, which was overtaken by ANSYS. Unfortunately, that overtake brought some serious problems in customer support etc. so, e.g. the old Ansoft website is partially still online, but not the support part, which should have been moved to the ANSYS website - but seems to have been forgotton... Needless to say, I am so happy about the ANSYS-Ansoft marriage...
ANSYS 13, Maxwell and HFSS are three different programs / software packages. You can buy and use them individually.
Since the integration on Ansoft in ANSYS you can buy a license for all Ansoft products in one.
I totally agree with roxxon about the "serious service problems", but I think they finally made it.
