Geotechnical Analysis | Stiffness Modulus Method | Generation of Soil Layers

Two definition types are available for the generation of soil layers from boreholes using the constrained modulus method:

Internally according to the solution of RF-SOILIN in RFEM 5

  • The soil layers beneath each surface element to be analyzed is internally approximated from the boreholes.
  • This solution corresponds to the method already used in RFEM 5 in the RF-SOILIN add-on module to determine soil layers.
  • This solution requires less calculation time during meshing. However, the determined layer boundary surfaces are not visible.

By generating and meshing 3D solids

  • The soil layers are created from boreholes by generating the soil solids, like in the 3D solution, with NURBS surfaces as layer boundary surfaces.
  • The soil solids are visible and meshed. The 3D elements are not calculated. Only the soil material is derived from them.
  • This solution requires more calculation time during meshing. The determined layer boundary surfaces are visible.

The selection is made by activating or deactivating the "Generate soil solids" option.
