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.
