There are different line types of varying degrees of complexity. Examples are polylines, arcs or NURBS lines, just to mention a few. According to the complexity of the line, it might happen that additional intermediate nodes are necessary for the line defnition. There are different line types. In addition, line loads and line supports can be defined at lines.
A local line coordinate system is assigned to a line where the x-axis is oriented towards the line. The other axes are adjusted to the global coordinate system wherever possible. Adjust the line coordinate system by right-clicking and selecting the option 'Reverse Line Orientation'. In addition, the line can be rotated in the line settings.
Entering in RFEM
Lines can be entered graphically and defined in detail in RFEM by using 'Insert' → 'Model Data' → 'Lines' → (select line type) → 'Graphically', by using the corresponding button in the toolbar or tables of the Data Navigator.

If the check box "Number of load increments" is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently.
The used method is based on a heuristic algorithm.
Frequently Asked Questions (FAQ)
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Which Dlubal programs do I need to calculate membrane and textile structures?
- Does a user-defined layer composition in RF-LAMINATE need to be shared separately with other users along with the RFEM model file or is this information stored directly in the RFEM file?
- I have modeled two nodes on a surface in RFEM. The results do not show the displacement at these two nodes. How can I obtain it?
- Which add-on modules and programs do I need for laminate and sandwich structures as well as cross-laminated timber (CLT)?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- How do I display the nodal displacements graphically?
- Are silos/tanks possible to export from RFEM into Revit?
- In connection with the calculation according to Theory III. Order, I get significantly smaller deformations than when calculating according to Theory I. or II. Order. How is this possible?
