A computer code has been developed which calculates the variation of some of the physical quantities of the gas of a disk galaxy while allowing the thickness of the disk to change. Using several different approximations for the interstellar medium, models have been computed which give substantial agreement with the observations of Jackson and Kellman which suggest that the half-thickness of the Milky Way is enhanced in the regions of the spiral arms. The models give additional predictions on the temperature, ionization fraction and cloud fraction which will be discussed. The code is also amenable to changes which allow for more sophisticated treatments of the input physics and in the galactic geometry.
