  Through mathematical models, it is possible to turn a problem of the physical
domain into the computational domain. In this context, the paper presents a
two-dimensional mesh generator in generalized coordinates, which uses the
Parametric Linear Spline method and partial differential equations. The
generator is automated and able to treat real complex domains. The code was
implemented in Python, applying the Numpy and Matplotlib libraries to matrix
manipulations and graphical plots, respectively. Applications are made for
monoblock meshes (two-dimensional shape of a bottle) and multi-block meshes
(geometry of Igap\'o I lake, Londrina, Paran\'a, Brazil).
