LRB Isolators' errors

[hbma]

Hi,
I have a 3D model of a bridge and have modeled LRB isolators between deck and piers and also between deck and abutments, using "LeadRubberX" command. While I run my model, the following error appears on screen. I do not know what is the problem with my model.
Error: "LeadRubberX::setUp<>-element:57
incorrect dimension of orientation vectors"

LeadRubber bearing only works in a 3d problem .. my guess is your NDM is 2.

I have written "model basic -ndm 3 -ndf 6" in my code.
I guess it is due to parameters <$x1 $x2 $x3> $y1 $y2 $y3>. However they are optional, I think I should accommodate them in my model. Moreover, I do not know how I should use them.
Thanks

well that error should only pop up if the node does not have 3 coordinates at the end .. post a small example (1 leadrubberbearing element) that demonstrates the problem and i will sort out what is up.

"element LeadRubberX 57 612 622 $fyi $alpha $Gr $Kbulk $D11 $D21 $ts1 $tr1 $n1"

Also, nodes 612 and 622 are defined as below, and they are of that nodes being fixed:
"node 611 0. 14. -3.
node 612 0. 14. -2."
I should mention that when I filled the arguments <$x1 $x2 $x3> $y1 $y2 $y3>, there were no more error like this.
