Dlubal software

Powerful, simple & intuitive

We are an authorized reseller of the German software developing company Dlubal Software GmbH in Bulgarien.

Dlubal Software GmbH has been developing structural analysis and FEM calculation software for more than 25 years. With over 6,000 client companies and 25,000 satisfied users in 71 countries, Dlubal programs are successfully in daily use in a wide range of industries and application areas.

RFEM

The FEM calculation program RFEM allows quick and easy modeling, static and dynamic calculation as well as design and modelling with beam, plate, disk, folded, shell and solid elements.

RFEM is the basis of a modular program family. The basic program RFEM is used to define the structure, materials and actions of plate, shell and member structures. Mixed models are possible as well as solid and contact elements.

RFEM provides calculation of deformations, internal forces, stresses, bearing forces. Add-on modules facilitate data input by automatic creation of structures and connections or allow further analyses and design according to different standards.

The modular concept allows the program package to be tailored to individual requirements. A later upgrade remains possible at any time.

The main program RFEM is also available as a light 2D version.

RSTAB

The software RSTAB is suitable for the calculation of 2D or 3D frameworks made of steel, concrete, wood, aluminum or other materials.

With RSTAB, the user simply and quickly defines the structural model and then calculates internal forces, deformations and support reactions. For the subsequent design, additional modules are available that take into account the material- and standard-specific conditions.

RSTAB forms the basis of a modular software system and allows you to intuitively model simple and complex structures by means of a sophisticated input technique. The powerful calculation kernel of RSTAB allows the linear and non-linear calculation of internal forces, deformations and support reactions.

For the design, additional modules are available that take into account the material- and standard-specific conditions. Thanks to the modular software concept, you can put together a program package that is tailored to your individual requirements. A later upgrade is possible at any time. 

The main program RSTAB is also available as a light 2D version.

Bim-orientation

BIM (Building Information Modeling) is a modern working method for the design and realization of construction projects, based on the networking of all parties involved in the design and construction process.

All relevant building data are digitally recorded in a three-dimensional building model. This model then passes through all design processes. For example, the CAD and structural analysis software does not use different models, but instead transfers them directly.

Dlubal enables its users to design according to BIM. Due to the numerous interfaces in the structural analysis programs RFEM and RSTAB, data exchange with industry-standard software (e.g. CAD programs) is easy and convenient.

 

Below you find a selection of interfaces that are integrated in RFEM and RSTAB by default.

By means of user-defined conversion files, you can define rules for materials and cross-sections (except for MS Excel and CSV).

Other programs

Cross-section programs

  • Thin-walled cross sections

The independently running program DUENQ determines the profile characteristics for any thin-walled cross-sections and calculates their stresses. A plastic design is possible.

  • Solid cross-sections

The DICKQ cross-section program can be run independently. The program determines the cross-section properties for any thick-walled cross-sections and calculates their stresses. In addition, reinforced concrete design according to Eurocode 2 and other standards is possible.

The cross-sections created by means of DUENQ and DICKQ can be imported into RFEM and RSTAB.

 

Standalone programs

  • Steel construction

The stand-alone programs KRANBAHN and FE-BEUL can be run independently from RFEM and RSTAB. KRANBAHN designs crane girders according to Eurocode 3 and FE-BEUL allows for buckling safety checks for rectangular plates according to EC 3.

  • Composite Structure

The VERBUND-TR program enables the design of composite continuous beams according to ENV 1994-1-1:1992-10 (the current EC 4 is currently being incorporated).

  • Timber construction

The individual programs RX-TIMBER carry out the verification of the load-bearing capacity, service ability and fire protection according to Eurocode 5 for various components (glulam beams, continuous beams, wooden supports, coupling purlins, frames, bracings and roofs).
