Line Releases

With version 5.05.0018, line releases are available in RFEM. You can access this new option in the Data Navigator.

Thus, it is possible to decouple elements connected to a line (members, surfaces, and solids) from each other. A new line is generated at the same place, transferring only the locked degrees of freedom. You can now also consider nonlinear effects.

First, it is necessary to create the line release type. Thus, the open degrees of freedom, spring constant, or possible nonlinearities are defined. Then, you can carry out the line release for members, surfaces, and solids on individual lines. In the same dialog box, you can also engineer the axis system of the release.

KB 001848 | Timber Column Design as per the 2018 NDS Standard in RFEM 6

Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

RWIND 2 is a program for generating wind loads based on CFD (Computational Fluid Dynamics). The wind flow numerical simulation is generated around any building, including irregular or unique geometry types, to determine the wind loads on surfaces and members. RWIND 2 can be integrated with RFEM/RSTAB for the structural analysis and design or as a stand-alone application.

This article describes the development of the Parametric FEM Toolbox and some of the possible workflows with this new tool.

In order to create a surface model with failing supports close to reality, an option called "Failure if contact perpendicular to surfaces failed" is available in RFEM 5 for contact solids under "Contact Parallel to Surfaces".

Feature 002423 | Displaying Results in Solids

The results of solid stresses can be displayed as colored 3D points in the finite elements.

Improved Calculation Performance by Optimized Consideration of Nodal Degrees of Freedom in RFEM

The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.

This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (for example, trusses and membrane structures).

This section offers useful information about general structural analysis and design as well as Dlubal Software programs.

Infotainment

Display extended strains of members, surfaces, and solids (for example, the important principal strains, equivalent total strains, and so on) in the Project Navigator - Results in RFEM as well as in Table 4.0.

For example, you can display governing plastic strains when performing the plastic design of connections with surface elements.

Frequently Asked Questions (FAQ)

Where can I find my customer number in RFEM or RSTAB?

Is it possible to define member nonlinearities for beam members?
For example, can I define a member that absorbs all internal forces, except for the compressive axial forces?

How can I exchange data between RFEM 5 / RSTAB 8 and Tekla Structures 2023?

I get a warning that a file created with RFEM, RSTAB, or RSECTION contains a virus or a Trojan horse. What should I do?

I design pipelines using the RF-PIPING Design add-on module. I have created a new prestress load case and loaded the piping with longitudinal displacement.
Is it possible to add this new load case to combinations that are generated automatically?

My Surface Book is recognized as a "Hyper V" virtual machine, so my local license does not work. What can I do?
