Help: EM Simulator package required for designing magnetic coupling
I am a research student. Now I am working on wireless charger based on coupled magnetic resonance. It is mandatory to simulate the circuit. Can somebody suggest the names of simulating software to measure magnetic coupling (or coupling coefficient). It is urgent.
You can look at CST EM Studio and Ansys Maxwell. I have used both. CST is a bit easier with a shorter learning curve, in my opinion.
As already posted in your other thread: I used ADS Momentum to optimize inductor shapes for wireless power transfer (Qi), and built an ADS Momentum-based inductor synthesis tool for a customer working on Qi.
For visualization of magnetic fields, I also used the ADS FEM solver engine. Not really relevant for optimization, but customers like the colorful field plots.
What is the link for this simulator? Any trial versions are available?
Your university might have the licenses already, these packages are very popular and there are special university license bundles.

Wireless power transmission in the kHz and low MHz range can be analyzed as pure AC magnetic problem without significant coupling to electrical and EM far field, no need for a full featured EM solver.
There are several free packages that work for the problem, e.g. FastHenry or femm (see https://www.edaboard.com/showthread....=1#post1581404 http://www.femm.info/wiki/HomePage).
Also, you can use Keysight's EMPro FEM or FDTD simulator

I think Maxwell of Ansys is more appropriate for Low Frequency EM problems.(I have never used but it's said..)
I have arranged a ANSYS student version. Is there any way to get some sample models on inductive/resonant coupling to study with.
I just downloaded a Ansys 18.1 student version (AIM) for my research work related to wireless power transfer. I opened the s/w and choose 'magnetics' icon. Now no tools are coming. How should i start? Every tutorial videos are starting with some pre-designed models. From where I can get geometry files?
This video may get you started:

I vote for FastHenry.
Also, you can try to use a solver called EZMod3D, mentioned in this article:
