Unit Weight

A Unit Weight greater than zero must be specified for each material in the Define Material Properties dialog. Unit Weight of a material is expressed as a force per unit volume:

Saturated Unit Weight

If a Water Table has been defined for a model, then you can define different Unit Weights above and below the Water Table for any material, as follows:

The Saturated Unit Weight option will ONLY be enabled if a Water Table exists.

NOTE: the Saturated Unit Weight is the saturated, bulk unit weight of the material, and should always be GREATER THAN the Unsaturated Unit Weight. The Saturated Unit Weight is NOT the buoyant unit weight of the material (i.e. the submerged unit weight under water) !!!
