Useful Program Features
Dlubal Software programs and add-on modules include a wide range of powerful features.
Since our software is subject to continuous development, we are constantly adding new features. In doing so, we also take account of our customers' wishes.
Why Dlubal Software?
If you activate the "Display shape" option in the shortcut menu, structural form changes of membrane surfaces are automatically focussed with the form-finding properties stored. This interactive graphics mode is based on the force density method.
The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the option "Update only materials, thicknesses, and sections." In this case, only the properties of the objects will be adjusted. Changes differing in material, surface thickness, and section are, however, not considered in this case.
The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
For member loads of the load type "Force", you can define eccentricities. You can apply the load eccentricities by means of an absolute or relative offset.
It is recommended to use the large deformation analysis to consider all effects of eccentric loads.
RFEM offers the following tables to display forces and deformations of hinges and releases:
- 4.45 Line Hinges - Deformations
- 4.46 Line Hinges - Forces
- 4.47 Member Hinges - Deformations
- 4.48 Member Hinges - Forces
- 4.49 Nodal Releases - Deformations
- 4.50 Nodal Releases - Forces
- 4.51 Line Releases - Deformations
- 4.52 Line Releases - Forces
The tables can be displayed in the prinout report. Moreover, the results in line hinges and line releases can be displayed graphically. It can be controlled by the Project Navigator - Results.
The reinforcement concept from RF-/CONCRETE Members can be exported to Revit. Rectangular and circular cross-sections are possible at the moment. The reinforcement bars can be modified afterwards in Revit.
Imposed line deformations can be defined for supported lines in RFEM. For example, foundation settlements can be simulated with this function.
Moreover, it is possible to define imposed rotations for lines.
RFEM provides the option to couple surfaces with the stiffness types "Membrane" and "Membrane-Orthotropic" with the material models "Isotropic-nonlinearly elastic 2D / 3D" and "Isotropic Plastic 2D / 3D" (add-on module RF-MAT NL required).
This functionality allows you to simulate the nonlinear strain behavior of z. Eg ETFE films.
In the RF-LAMINATE add-on module for RFEM, the design of torsional shear stresses is possible in the superposition of net and gross cross-section values. The design is effected separately each in x- and y-direction. The loadings of the intersection points of cross-laminated timber panels are designed.
By using the integrated module extension RF-/STEEL AISC Warping Torsion, the design according to the Steel Design Guide 9 can be performed in RF-/STEEL AISC.The calculation is effected with 7 degrees of freedom according to the warping torsion theory and allows the realistic stability design including the consideration of torsion.
