# Generate Mesh from Soil Zones/Profiles
GSA provide two methods for soil structure analysis. The legacy version defines the soil with profiles and zones. For a finite element approach to modelling the soil the needs to be meshed with brick elements.
# Definition
Element Size
This defines the target size for the elements in the soil mesh.
Boundary Conditions
The soil boundary in the horizontal direction can be modelled in different ways – either restraining the boundary nodes or be creating infinite elements around the boundary.
Tolerance
The limits the distortion in the mesh that is acceptable when moving from one soil zone to another.
