Need a suitable software for simulate microstrip filter

Hi
I am a student of telecommunication and working on a project in university.
I designed a Quasi-Elliptic filter with microstrip line. I want to simulate it now.
I simulated my design with HFSS, but it is very slow. EM simulator of AWR
( Microwave Office) is slow too for my structure and i cant optimize it.
Schematic circuit of AWR is not suitable and dont use correct model but it is very fast.
I dont know what must I do ? and which kind of software i must use?
I searched more about it. I found that Ansoft EM-simulator ensemble and Agilent ADS-Momentum is suitable for simulating my filter.
But i dont have any access to these softwares in Iran.
If someone have these softwares I ask that send them for me.
I need them so much . PLEASE send them to me as soon as possible, if u have any of them.
This is my email : sahar13_ee@yahoo.com

Thanks alot
