Take your structural design one step further. RFEM 6 and RSTAB 9 support now a new file format for structural design, Structural Analysis Format (SAF). For this, both programs allow for the import as well as the export. SAF is a file format based on MS Excel, intended to facilitate the exchange of structural analysis models between different software applications.
When exchanging data with Advance Steel using *.smlx files, the interface is detected automatically. This means that *.smlx files can be created even if no version of Advance Steel is installed.
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 check box 'Update only materials, thicknesses, and sections'. In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
The ACIS SAT file format is smaller than other 3D formats, saving you time when importing and exporting models. The export currently supports the ACIS 7.0 format.
In addition, SAT is considered to be particularly robust, and all geometry and topology data, where relevant in RFEM, are retained in the highly accurate SAT models.
There are also improvements in the data exchange to make your work process easier. In addition to the import of IFC 2x3 (Coordination View & Structural Analysis View), the import and export of IFC 4 (Reference View & Structural Analysis View) is now supported.
In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.
With the RF-DYNAM Pro - Equivalent Loads add-on module, it is possible to generate load distribution automatically in accordance with a mode shape and export it as a load case to RFEM.
Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported to Revit as reinforcement objects via the direct interface. To do this, you can optionally select surface, rectangular, polygon, and circular reinforcement areas in RF-CONCRETE Surfaces. In addition to bar reinforcement, it is possible to export mesh reinforcement.
Always keep an eye on your results. In addition to the resulting load cases in RFEM or RSTAB (see below), the results from the aerodynamics analysis in RWIND 2 represent the flow problem as a whole:
Pressure on structure surface
Pressure field about structure geometry
Velocity field about structure geometry
Velocity vectors about structure geometry
Flow lines about structure geometry
Forces on member-shaped structures that were originally generated from member elements
Convergence diagram
Direction and size of the flow resistance of the defined structures
These results are displayed in the RWIND 2 environment and evaluated graphically. The flow results around the structure geometry in the overall display are rather confusing, but the program has a solution for this. In order to present clearly arranged results, freely movable section planes are displayed for the separate display of the 'solid results' in a plane. Accordingly, for the 3D branched streamline result, the program presents you an animated display in the form of moving lines or particles in addition to the static one. This option helps to represent the wind flow as a dynamic effect. You can export all results as a picture or, especially for the animated results, as a video.

This way, the program allows you to control and clearly manage the exported data. You can export the stored formulas directly in the table or as a separate table, as in the case of the used parameters.
Various languages are available for the results included in a printout report: English, German, French, Spanish, Italian, Czech, Slovak, Hungarian, Polish, Dutch, Portuguese, Russian, and Chinese. You can create further language versions individually.
It is possible to import additional texts as RTF files. Page numbering can be configured as well in order to use prefixes, for example. Furthermore, you can export the printout report as an RTF or PDF file as well as in VCmaster.
Of course, RFEM 6 also offers extensive language settings for our customers from all over the world. Various languages are available for the results in your printout report: English, German, French, Spanish, Portuguese, Italian, Czech, Polish, Russian, and Chinese. You can create further language versions individually. You can easily import additional texts. Configure the page numbering to use prefixes, for example. Furthermore, you can export the report as a PDF file.
Rely on the Dlubal programs even in windy matters. RFEM and RSTAB provide a special interface for exporting models (that is, structures defined by members and surfaces) to RWIND 2. There, the wind directions to be analyzed for your project are defined by means of related angular positions about the vertical model axis. Furthermore, the elevation-dependent wind profile and turbulence intensity profile are defined on the basis of a wind standard. These specifications result in specific load cases, depending on the angle. For this, the fluid parameters, turbulence model properties, and iteration parameters that are all stored globally are helpful. You can extend these load cases by partial editing in the RWIND 2 environment using terrain or environment models from STL vector graphics.
As an alternative, you can also run RWIND 2 manually and without the interface application in RFEM or RSTAB. In this case, the structures and terrain environment in the program are directly modeled by imported STL and VTP files. You can define the height-dependent wind load and other fluid-mechanical data directly in RWIND 2.
Due to its versatile applicability, RWIND 2 is always at your side to support you in your individual projects.
