Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
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 (e.g. trusses and membrane structures).
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".
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.
- How do I get the current authorization file for RFEM 5, RSTAB 8 and other stand-alone programs?
- Why are the free line loads not displayed completely at certain locations after copying them, for example?
- Can I also use RWIND 2 with RFEM 5/RSTAB 8?
- I cannot create a new file. The menu item is grayed out. What can I do?
- Is it also possible to consider friction at nodal support in RFEM or RSTAB?
- Where in the Dlubal extranet can I download my RFEM / RSTAB authorization file?
- How can I display more information about member end hinges in a graphic?
- I have a model with crossing line releases/line hinges and I obtain implausible results.
- I deleted my shortcut from the viewer. How can I restore them?
- Can I create a visibility from objects even though the function is grayed?
