And for this we must first decide what kind of elements will use. And this pattern will be unique to each new problem. The overall pattern of elements is referred to as the finite element mesh. We replace the single complicated shape with an approximately equivalent network of simple elements. The finite element method takes advantage of this fact. However the equations can be solved for very simple shapes like triangles or rectangles. The equations describing the distribution of structural stresses are known but they can’t be directly solved for a complicated shape such as a bridge. Finite element breaks a complex problem into simpler problem and uses a mathematical glue to join the solutions.Īn engineer designing a bridge will need to know how the proposed structure will behave under load. The Finite-Element Method (FEM) is a computational method/technique developed by engineers used to obtain an approximate solution to engineering problems.
RFEM has interfaces for Industry Foundation Classes, CIS/2 and others. Thus, the bidirectional data exchange between RFEM and the programs Tekla Structures, Autodesk Revit and Bentley Systems applications (ISM) is possible.
RFEM integrations BIMĭue to a wide range of interfaces, RFEM provides perfect interaction between CAD and structural analysis programs in Building Information Modeling (BIM). Add-on modules – Tensile membrane structuresįor more information please visit.Steel and aluminium structures add-on modules.Reinforced concrete structures add-on modules.The modular software concept allows you to compile a program package tailored to your individual needs. The corresponding add-on modules facilitate data input by automatic generation of structures and connections or can be used to perform further analyses and designs according to various standards. RFEM provides deformations, internal forces, stresses, support forces, and soil contact stresses. The program also allows you to create combined structures as well as model solid and contact elements. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. RFEM is a finite element analysis program for quick and easy modeling, structural analysis and design of 2D and 3D models consisting of member, plate, wall, folded plate, shell, solid, and contact elements.ĭue to the modular software concept, you can connect the main program RFEM with the corresponding add‑on modules in order to meet your individual requirements.
