Quasi-static stellar evolution has been tackled
numerically as early as electronic data-processing entered the
field of astronomical research some fifty years ago.
Despite some improvements in
the description of turbulence, opacities, or in the equation of state,
the results presented by different authors still
show a rather wide
spread in results. This poster tries to provide some
hints on the reasons of these discrepancies and tries to
point at difficulties that may arise from using theoretical
stellar evolutionary tracks for mass/age determination of
observed stars.
