      Hi,

      I want to medel h2/o2 catalystic reaction on Pt. my problem is in calculation of site density and surface to volume ratio. 
      i have defined Pt as site species. 
      With my calculations base on material properties (0.5% wt pt on Al2o3 plettes of 3.2 mm and 90 m2/g) i cannot converge solution or i have high H2 conversions. In this contour H2 mass fraction is shown and reaction is just at the beginning of the porous medium.
