First Steps with RFEM
Question
I get an error message saying that there is no material assigned to one or more point elements. How can I solve the problem?Answer
In order to prevent the error message (Figure 1) to appear, and ensure that the calculation will start, it is necessary to assign the material to the corresponding point elements as follows:
Figure 01 - Error Message "Material Not Defined"
- Right-click the entire cross-section: "Reduce Cross-Section into Elements," see Figure 02.
- Select the corresponding elements or all point elements with the "Insert" status by using the Views navigator, because these can be only used to define the material (in contrast to the point elements with the "Remove" status).
- Assign the corresponding material and click OK to confirm, see Figure 03.
- Deactivate the visibility.
- Select all elements and right-click one of the selected elements: "Create Cross-Section from Selected Elements," see Figure 04.

SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
