Hi,

I want to add to my model 1d elements like a rod:

How can I add it to my input deck and what is a full syntax of a key word?

Exactly, what kind of 1D element do you want to use ? There are several types available in CalculiX:

  • beam
  • truss
  • spring
  • dashpot

To define them you need to follow the standard scheme used for all elements:

*NODE
...
*ELEMENT, TYPE=..., ELSET=...
...

Then you have to assign correct section / property reference:

  • beams: *BEAM SECTION
  • trusses: *SOLID SECTION
  • springs: *SPRING
  • dashpots: *DASHPOT

How I mentioned above - FE rod, but from your list I guess it will be truss.
So the syntax is:

*ELEMENT, TYPE=TRUSS
[truss id], [node 1], [node 2]
ELSET,ELSET=TRUSS
[truss id]
*SOLID SECTION,ELSET=TRUSS,(?)MATERIAL=steel
and it’s all?

Almost like this but it has to be a specific element label and you need to specify the cross-sectional area for truss elements under *SOLID SECTION. For example:

*NODE
 1, 0, 0, 0
 2, 2, 0, 0
*ELEMENT, TYPE=T3D2, ELSET=TRUSS
1, 1, 2
*SOLID SECTION, ELSET=TRUSS, MATERIAL=STEEL
