ZeroLength element

Hello everyone,
is it possible to define a zerolength element for 2 nodes with differing dof :?
When I do so, OpenSees stops working with a warning sign with the following error : nodes 1 and 339 have differing dof at ends for ZeroLength 520
any suggestion will be greatly appreciated
thanks :)

Re: Error using Brick Element

seems like stdbrick element should not be defined with -ndm 3 -ndf 6 :?
when I define it with -ndm 3 -ndf 3 , its works just fine :!:
But I need -ndf 6 for my analysis as I am supposed to use a shell element which cannot be defined with -ndf 3. what should I do ??
please help :(
