3D spiral inductors simulators, which one ?

[matte87]

Hi everybody,
I'm working on 3d Spiral inductor simulation to extract Z parameters and study mutual inductance between two inductors. I want to focus on the high frequency resistance effects...It would be also useful create some scripts to build automatically the geometries giving some parameters.
I'm a little bit confused about all the existent EM simulator. On the web I founded a lot of different simulators like Momentum ADS, Maxwell 3D, HFSS, ASITIS, CST, Comsol (why not...)..

Can you give me some differences about all these simulators? What is the difference between them? Which is the best for my goal?

Thank you

...any help?

Each simulation tool has its own pros and cons... If u are looking for 3D simulation --HFSS/CST are the way to go...

Thank you for your reply Venu! I'm already using HFSS...I have another question about post processing in hfss. I would like to have a look at the current distribution inside the inductor's conductors . Do you know if there's any way to project the current density on a conductor perpendicular plane?
Thank you

Also a easy way to extract z parameters is to use momentum of ads as 2.5 EM-simulator or the included fem (3d-sim) - simulator. you can easlily use the calculated s- parameters in any schematic and play with them.

Hi,
I would like just to tell you that HFSS can't be used for low frequency applications, that's why all simulations I've done are not correct!

So, coming back to my question the correct answer would have been : no, you cant if your frequency is low! I spent almost two months with this software and im really disappointed.

Can you upload such a problem, with which you got this conclusion? It could be another tools can be applied with better success here, but it is difficult to estimate without given specifications.
