  VD reactions: 1) H2BO3-+H+ => H3BO3; 2) 5I-+IO3-+6H+ => 3I2+3H2O; & 3) I2+I- <=> I3- it is three step reactions. are these settings right
  Are these settings right? Inlet diffusion must be selected? and under Chemsitry solver... None or Stiff chemistry must be slelected .I have tried None it doesnt work. I have taken all fluid properties similar to water except I have used their respective Mol.wts. I have a UDF for defining the Reaction kinetics from journal paper(as we dont have arrhenius rate constnts )which I compiled and loaded. I need help with this reaction. Any help, suggestion feedback will be highly appreciated, Thanks

  Hello,
  What issues do you face while running the simulations? Does it diverge? Or do you get some kind of error? If so, please let me know.
