We describe an ionization gasdynamics code to study astrophysical systems where the gas-dynamics must be computed in tandem with the photo-ionization from a source. We use it to compute a model of the wind-blown bubble around a 40 solar mass star, and from this, to accurately compute the X-ray emission from the bubble. We outline our methods and techniques for these computations, compare them with previous calculations, and show how they relate to observations. Our simulated X-ray spectra suggest that X-ray nebulae around massive stars may not be easily detectable, consistent with observations.
