Hi sir, i jave similar problem as Berk, i have 1 layer of infill, 1 layer of silt ans and another layer of clay. How should i inpuy for all these layer in this programme ?
Hi John, you just define three interfaces. The topmost interface represents the terrain and the other two represent the boundaries between the three soil layer. The model's bottom boundary is created automatically at prescribed depth below the deepest interface. Then you run standard stress analysis with whatever load you wish. Please refer to engineering manual no. 21 "Terrain settlement analysis" on www.finesoftware.eu/engineering-manuals/?productId=all&predatorId=GeoFEM&langId=en, where you find more details and step by step tutorial.

Hi i have three soil layers; clay at the top, sand in the middle and same clay at the bottom. I want to find consolidation settlement of those clay layers only as well as instantenaous settlement for all those layers but the program wants me to specify only one range of layers so im confused. Also, it seems the program uses the overconsolidation formula while calculating settlement for sand layer too. I thought i didnt need to know compression index and void ratio to calculate sand layer's settlement but the program wants that
Hi Berk, GEO5 FEM always calculates the entire displacement field for all layers. If you want to calculate the instantaneous settlement you should use an undrained material model for the clay layers. Check Topo->Settings->Advanced material parameters and then select "undrained" in the Soil dialog. If you want to calculate the settlement after the pore pressure has dissipated, use a drained material. This is the default option. If you want to calculate settlement in between these two limit states, you should go with GEO5 FEM - Consolidation module, that allows for coupled, time-dependent analysis. This will give you the evolution of displacement and pore pressure. Feel free to send us your model to hotline@fine.cz so we can comment on it in more detail.

Hi John, the interface is simply a polyline defining a boundary between soil layers. For details please refer to www.finesoftware.eu/help/geo5/en/interface-04/. Beside interfaces you can use free lines to define more complex geometry. For more details on free lines see www.finesoftware.eu/help/geo5/en/free-lines-02/. Interfaces should not be confused with contacts, which are used to model relative displacements between two soil bodies or between a soil body and a beam. For contacts, see www.finesoftware.eu/help/geo5/en/contacts-01/. Hope this helps, best regards Fine team
The name of the software is GEO5 from Fine company, more information you can find on our website www.finesoftware.eu/geotechnical-software/. Best regards, Fine team
