v20 v21 7 7 Jonathan what would it take to do a test of this? 8 8 9 Ionizing source in media with initially low optical depth but tau builds up till it hits 1.9 Ionizing source in media with initially low optical depth but tau (exp(tau) ??? ) builds up till it hits 1 (fully ionized??). 10 10 11 11 We are basically trying to do the strongmen(Stromgren?) sphere problem. … … 76 76 == related code == 77 77 78  tau  optical depth tau=sigmaH*nH + sigmad*nHII   79  scale    80  emtau  exp(tau)   81  value range    82  ionization rate  flux*(1exp(tau))/dx  has computationa units of number per volume per second  83 84 85 78 86 {{{ 79 87 ! Goal is to take input flux and integrate equations across grid to find ionization rate and heating rate
