Model Type

Select the model type. For a 3D model, the gravitational direction can be set as Y or Z and for the 2D or axis symmetric model, the gravitational direction is fixed in the Y direction.

Unit System

Setup project unit for force/length/energy/time. Selected system of unit can be changed anytime during the modeling process and on the status bar in the lower right-hand corner.

The provided unit systems are as follows.

<Force>         <Length>        <Energy>         <Time>

When importing a geometric shape from an DXF(2D/3D) file, AutoCAD does not have a length unit so, the imported shape follows the units set on the program.

When importing a CAD geometry, the length unit of the object model can be separately specified by importing the length unit file.

Initial/Water Parameters

When converting the mass of dynamic loading and self-load by material’s unit weight or calculating pore water pressure, unit weight of water and acceleration of gravity is set as variables. Initial temperature is a variable that is assigned when thermal load is inserted. The difference between set initial temperature and inserted thermal load would be converted into weight and assigned.

Additional input for thermal analysis is provided:

Specific Heat of  Water: determines amount of heat (energy) can be stored in the pore water per unit of mass.

Conductivity of Water: determines rate of heat (energy) can be transported in the pore water.

Conductivity of Ice: determines rate of heat (energy) can be transported through ice.

Latent Heat of Water: amount of energy  required for water phase change (from liquid to solid state and vice versa).

* For 2D analysis, the planar deformation thickness of the ground needs to be directly input to be applied to the analysis. Generally, the unit width is input, with respect to the set length unit system.
