Rana,

please pay attention how your email is formatted.... All lines were
concatenated together, and I had problems with reading your
questions. Please have a look at http://www.catb.org/~esr/faqs/smart-questions.html

what is the question exactly? The formula used is already written here...

you can put there any number you want.

see answer by Jerome.

> 2.sigma_iso = 50000..is it isotropic pressure?  I have checked the following reference.

yes but it depends which walls are activated, see for example in the xml file "wall_bottom_activated", etc..., and you can set any value that you want.

That's a good place.

SDEC manual does not apply to YADE. Of course YADE is based on SDEC
and uses the same formulas, but developing with YADE is completely
different than with SDEC.
