Currently, there are 2 modules available for geotechnical calculations.
Foundation Design makes the EC7 code check of the foundation load carrying capacity.
3D Soil calculates the interaction between the soil properties and the structure.
The modules can work together or individually.

Building stresses are usually analyzed in detail, while the foundation is modeled with springs to simulate the underlying soil deformation. These springs - which are often assumed to have the same characteristics over the entire foundation, does not give a true picture of how the soil reacts to the loads.
With FEM-Design 3D Soil, the different soil layers can be defined to create a 3 dimensional soil volume, which is analyzed simultaneously with the overlying structure. This is an innovative way to take into account the soil deformation and thus obtain a proper stiffness analysis and cumulative load calculation.
The module is a unique innovation that is not on the market today. This may change both the methodology and approaches to assess the building settlement. Geotechnical properties can not be represented by the springs properly, states Lars. FEM-Design 3D Soil models soil with 3D finite element and becomes a construction material like concrete, steel, wood or other materials. The analysis combines these materials in a single calculation.This gives a much more accurate view of soil deformation.
EC7 foundation design checks the load carrying capacity of your foundations. It checks for both compression and sliding.
Everything is presented like hand-calculations to make sure, that this is not a 'black box'.
Available national annexes are Danish, Finnish, German, Hungarian, Norwegian, Polish, Romanian, Swedish and British. Concrete design also has the “clean” Eurocode without national annexes.
