about (2). It can brings to some mistake IMHO. As you are in charge of setting moments lenght, it could result in a very low accurate evaluation. Isn't it?

Donno if it's the right place to ask but: any project concerning a MacOS compatible version of OSees (Even an OpenSees LT)? Or maybe an app running on iPAd? You know... I spend a lot of time of my days on trains (home-university) and it would be useful to have something portable. Well, just asking anyway. Do not spend to much time on it

Just wondering: why do you need a zero lenght element? What kind of model are you building?

I hope I'm not wrong but I have seen a textbox where you can specify it after the poisson's ratio. Just let me check again. I had the same problem and it drived me crazy.

Hei Sumit Jindal. Are you using the "white loop" module? Can you give us some more infos abou your soil model? I will try to compare it with my experience and give you some feedback. Bye from Italy
