hi,
how could i set celas elements allowing motion in only one direction ? if i select DOF 3 does it mean it will allow displacement only in z- direction?
Hi,
regarding to OS reference guide:
- Dof (C1, C2) : dof in disp coordinate system (CD field of GRID)
normally CD=0 so dof3 means stiffness follows z-direction of basic coord system
to set celas follows an optional direction, create a system and assign it as 'disp system' of nodes of celas

If your requirement is to define stiffness in more than one direction.
1. By creating as many CELAS elements as the desired number of directional stiffness
2. By simply creating CBUSH elements where you can define 6 directional stiffness
The model with CBUSH should be simpler and work properly.

I have a question on this topic. What happens with the stiffness direction if the two nodes of the CELAS1 don't belong to the same coordinate system?

It could mean that forces will be transmitted with an abnormal way.
Like I kick your ass but make you sit down !

The force would not correspond to the extension right? You would get a force in the element based on displacements in two different directions.
