Problem in recognizing the brick8N

[kgkoktsi]

Hi!
I'd be grateful if anybody knows how the brick8N can be read by the opensees.
When I write the following script:

wipe;
model BasicBuilder -ndm 3 -ndf 3;

# nodal coordinates:

node 1 1 1 4
node 2 -1 1 4
node 3 -1 -1 4
node 4 1 -1 4
node 5 1 1 2
node 6 -1 1 2
node 7 -1 -1 2
node 8 1 -1 2
node 9 1 1 0
node 10 -1 1 0
node 11 -1 -1 0
node 12 1 -1 0

puts "Nodes Defined"

fix 9 1 1 1
fix 10 1 1 1
fix 11 1 1 1
fix 12 1 1 1

puts "Fixities Defined"

nDMaterial ElasticIsotropic3D 1 1800000 0.25 2.243

puts "Material Defined"

element Brick8N 1 1 2 3 4 5 6 7 8 1 0 0 0 0
element Brick8N 2 5 6 7 8 9 10 11 12 1 0 0 0 0

puts "Elements Defined"

I don't receive the final message "Elements Defined". But when I change the type of the brick element to SSPbrick everything is fine. Why is this happening?
Thanks!

brick8N is removed from OpenSees and that is why it is not working.

Vesna, thank you very much!
