Transfer function laplace.

The Laplace equation is a second-order partial differential equation that describes the distribution of a scalar quantity in a two-dimensional or three-dimensional space. The Laplace equation is given by: ∇^2u(x,y,z) = 0, where u(x,y,z) is the scalar function and ∇^2 is the Laplace operator. a LAPLACE or POLE function call in a source element statement.
