Analysis & Design Software for Laminate, Sandwich, and Cross-Laminated Timber (CLT) Structures
3D Finite Element Analysis and Design
Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Wind Simulation & Wind Load Generation
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
Design of Laminate Surfaces
RF-LAMINATE performs stress and deflection analysis of laminate surfaces under consideration of shear coupling (cross‑laminated timber elements, fiberglass, carbon, and so on).
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.
