====== COUTR ======

===== Description =====

1D truss bar or oedometer. \\ \\ {{  :elements:coutr.png?150|}}
The element is defined by 2 nodes. It associates conduction or flow with mechanics. The stress field (truss bar) or strain field (oedometer) is uniaxial. \\

Element type: 204 \\
Implemented by: R. Charlier (1988)
