XFEM4U is a 3D FEM calculation program for 3D frames and plates. The calculation method is Geom.
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.

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.
