XFEM4U

XFEM4U is the MOST intuitive structural analysis and design software for 3D models of any structure. Consider, for example, a calculation of 3D frameworks in steel and/or wood, concrete beam grids, foundation slabs on an elastic soil, point-supported concrete flat slabs, walls, and so on. Whether or not combined in one model.

It is developed in close cooperation with the users of the software.

Geometry

• Point, line, surface supports

FEM/Solver

• 3D Finite Element Method(FEM)
• New powerful matrix/equation solver written in C#
• Modern powerful meshing tool
• Create local mesh refinements
• Used hybride element type is based on the latest insights from engineering science.
• Geometric Linear(GL) and Geometric Non-Linear(GNL) second order calculation
• Physic Linear for Steel and Wood
• Physic Non-Linear for Concrete(Stiffness based on M-N-Kappa)

Loads

• Load Cases/Combinations user defined or using the Eurocode
• Beam load, plate load, free surface load, node load, free point load
• Forced node displacement
• Surface load can be used for load distribution to beams

Interface

• Multiple languages are available: English, German, Spanish, Italian, Norwegian and Dutch
• CAD like user interface intuitive modern and fast
• Colors, text height fully customable
• 3D OpenGL Graphics

Standards

• Eurocodes are integrated where applicable
• Dutch, German, UK, Belgium and Italian National Annex of the Eurocodes are integrated
• Partial factors are based on consequence class and NA
• Imperfection in 2 directions
• Dutch specific features:
  • NEN 8700 integration
  • Old rebarsteeltypes(FeB220,FeB400) are integrated
  • Earthquake calculations using the NEN-NPR 9998

Concrete

• Calculation of concrete beams using the Eurocode EN 1992-1-1
• Checks ULS and SLS
• FEM Calculation of reinforcement in plates based on all internal forces(M,N,V) using the latest scientific insights.
• Using the 3-layer model
• Shearforce reinforcement in plates is calculated as well

Steel

• Integrated Eurocode EN 1993(class 1-3 profiles)
• Global buckling stability check using GNL(Second-order analysis)
• Steel optimization module
• ca 2700 different steelprofiles integrated.
• Built-up section
• Deflection check including pre-camber
• Integrated steel connection module. Beam-column moment connection can be calculated and the trilinear rotational rigidity diagram is used for the momentdistribution

Timber
