Electrical current in swimming pool - QuickField simulation example
In this example we simulate a pool with a faulty underwater lamp that is a source of leaking electricity. The pool walls are covered with low conductivity ceramic tiles, so the only sink for the electricity is the grounded ladder. A dummy is immersed in the pool with both hands touching the ladder.

Simulation problem
Problem Type
3D problem of DC conduction.
Electrical conductivity values are taken from the book by G. S. Cargill III "Electric Shock Drowning: Causes and Prevention".
Water electrical conductivity is 0.15 S/m, body electrical conductivity is 0.12 S/m
Lamp voltage is 120 V, ladder is grounded.
Calculate the electric potential distribution in the water and current through the body.
We use a simplified human body model so the problem can be constructed by extrusion from the plane.
The lamp is operating at AC voltage. At 60 Hz frequency the displacement component of the electric current is negligible, so we run the analysis at DC voltage.
Electric current through the thorax is 14.7 mA.
