When I analyze a quiet complex spatial structure, error information warn that: the direction of the beam element is
not correct.
From abaqus document 26.3.4 I know we can
nominate the direction of beam element by adding additional node.It is clear
that this node should be off the axis of the element,any additional constrians?
May I define a random node in the space
which is far far away from my structure, then I add this node as unique
additional node?
*node
1,1,0,0
2,5,0,0
**additional node
10000,50000,50000,0
*element,type=B32
1,1,2,10000
.....
