Internal forces acting within a solid material are represented by stress fields. By applying the Divergence Theorem, civil engineers can relate the external loads applied to a structure to the internal stresses distributed throughout its volume. Geotechnical Engineering and Groundwater Flow

Using surface integrals (flux) to calculate electric fields generated by static charges. Internal forces acting within a solid material are
3. Civil and Structural Engineering (Stress and Thermal Analysis) This allowed her to place cooling vents precisely
. By calculating the temperature gradient (a vector pointing toward the steepest increase in heat), she could see exactly how thermal energy was moving through the alloy skin. This allowed her to place cooling vents precisely where the "heat flux" was most intense. The Power Check
For incompressible fluids like water flowing through a mechanical pump, the divergence of the velocity field is zero (
