I have already the Xcode project in xcode 5.1.1, and i am unable to add .xcdatamodel file as descriped in the below link.

Ie:
From Xcode, control-click on the Resources fold inside the Groups & Files pane
Where the Resource Folder available?. I do not see any folder in the project navigator?
did i miss anything to look into ?
http://wiresareobsolete.com/2009/12/adding-core-data-existing-iphone-projects/ is good enough to add core data model. you have to add new file -> core data-> data model. this will give you core data model. There is no need of resource folder.
If the Resource folder is not there you can create it. File->New->Group (or right click on the project navigator -> New Group). Its is a folder for grouping your files(All the resources like images,sounds will usually put it in Resource folder) nothing more than that. Some Xcode's will create it for you while creating the project, otherwise you could create it.
It doesn't matter .xcdatamodel file is in resource folder or not. But it makes sense if you have grouping like Source, Resources or logical grouping also
