For the settlement calculation in the RF‑SOILIN add-on module, the specific weight gamma and gamma,sat are required for the soil. What do I need the value gamma,sat for, and how is it assumed in the calculation?


The value $\gamma,_{sat}$& corresponds to the weight of the saturated soil and can be adjusted in the settings of material parameters, if necessary. If there is groundwater in a layer, the weight of the saturated soil $\gamma,_{sat}$ is automatically reduced from this layer by the weight of groundwater (10 kN/m³). Above this layer, the stresses are calculated with the specific weight of the soil.
