Structural FEA Software RFEM 6 | Modeling
Useful Tools for Fast Generation of Structures
"We are completely satisfied with RFEM and with Dlubal Software team too. Keep it up!
We are in contact with a lot of engineers and with the team of research of structural wood at the Santiago of Compostela University and always talk about RFEM like the software of reference."
“I really enjoy working with Dlubal Software programs. The structure generation and modification can proceed smoothly:
- Manageability of functions in the menu and movability in space
- Data transparency: checks, options to modify and transfer data
I am happy that I switched over to Dlubal Software!”
Modeling in RFEM 6 is easy and effortless for you. This is ensured, among other things, by useful auxiliary functions and tools for generating snow and wind loads, for example. It is also possible to consider member nonlinearities (yielding, tearing, slippage, plastic hinge, and so on), as well as couplings or member and surface eccentricities.
Discover the extensive cross-section and material libraries. These make it significantly easier for you to model surfaces and frameworks. You can filter the databases and expand them with user-defined entries. Special profiles from RSECTION can also be easily imported and calculated.
A clear display is a prerequisite for your efficient and fast work with the program. Select user-defined views from different angles to facilitate the result evaluation. Using "visibilities", you can also divide the model into user-defined and generated partial views that fulfill certain criteria. It is thus possible, for example, to only activate the surfaces of a specific material or members with a particular cross-section for the display.
There are many options available for simple input and modeling. Your entry is made in the 1D, 2D or 3D model. Member types such as beam, truss, or tension member make it easier for you to define member properties. For example, you can select the types Standard, Without Thickness, Rigid, Membrane and Load Distribution for modeling surfaces in RFEM.
In addition, various material models such as Isotropic are available in RFEM | Linear elastic, orthotropic | Linear elastic (surfaces, solids) or isotropic | Wood | Linear elastic (bars) available.
Do you want to process recurring systems efficiently? Then the parameterized input is recommended. You can create structures depending on certain parameters and adapt them precisely to the new situation by changing the parameters.
If you are working with nonlinearities, this feature is best suited to assist you. For example, you can specify flow, friction, cracking and slippage for member end hinges and supports. In addition, special dialogs are available with which you can determine the spring stiffness of columns and walls from the geometry specifications.
Planning with members is also made easier in the programs by means of specific functions. You can arrange members eccentrically, embed them elastically, or define them as rigid couplings. Sets of members make it easier for you to arrange loads on several members.
In RFEM, you can also define eccentricities of surfaces. Here you can also convert nodal and line loads into surface loads. Divide surfaces into faces and members into faces as required.
Do you want your structures to remain upright even in wind and snow? Then rely on the load wizards for surfaces and frameworks. You can now generate wind loads according to EN 1991-1-4 and snow loads according to EN 1991-1-3 (as well as other international standards). The load cases are generated depending on the roof shape.
This feature helps you stay flexible in your planning. You can adjust the numbering of structural objects such as nodes and members later. The objects can be automatically renumbered according to your chosen priorities (axis directions).
Always keep track of your model. The model control quickly detects any input errors such as overlapping members or identical nodes. You can automatically join intersecting members as you enter them. Members can also be lengthened or graphically divided. You can also use the measurement function in RFEM to determine lengths and angles of members and surfaces.
If you work with loads, you will find a selection of helpful functions here. A variety of load types are available for member and surface loads (force, moment, temperature, pre-curvature, etc.). You can assign member loads to members, sets of members, or lists of members. In the case of imperfections, skewing and pre-curvature can be determined precisely according to Eurocode, the American standard ANSI/AISC 360, the Canadian standard CSA S16, etc.
