This section defines the spatial and dimensional settings for the model

Problem Dimensions

The selection of the problem dimension depends on the geometry and physics of the problem.

2D (Plane-Strain): Used for problems that assume deformation occurs in a plane.

2D Axisymmetric:Suitable for problems with rotational symmetry around a central axis, such as cylindrical soil layers or tunnel excavations. This option significantly reduces computational costs while maintaining accuracy for symmetric problems.

3D:Used for fully three-dimensional problems, offering the most accurate representation of geometry and loads but requiring more computational resources.

Units

Allows users to define consistent physical units for parameters such as length, force, and time. The default units are kilonewtons (kN), meters (m), and seconds (sec). Ensures that all input values conform to the selected units, preventing calculation errors.
