At the moment I cannot log in to the CAELinux main site (forgotten password?). So I am sorry that I could not react to your question/remark on the forum regarding the changing in Wiki. I have not problems with that: this is a public site. So please continue to change and improve the contributions. I like to have interaction with other readers to get new ideas or improved ways to perform calculations.
I will try to use XMGrace. It sounds like a nice application.
kind regards - kees
