Its been a while that I have been looking for good softwares to perform airplane stability analysis.
I have worked on XFLR5 which is good enough, but I am looking for something better.

Please help me out!
Thanks in advance

Try XFLR.(Search for Xflr v5)
It is an open source tool and is easy to use and has good solver for acceptable results.

Try AAA. Advanced aircraft analysis(AAA) is good software for aircraft analysis.

Ansys is the best for structural analysis.Try it,but its not opensource.

Thank you for your reply.
XFLR and ANSYS are something we already use.
I would like to know about AAA and how to download and install it?
It would be great if someone could post a link.

Thank you!
