Species Transport model with eulerian multiphase model

      Hi all


      Can I model a species mixture as a granular phase in eulerian multiphase model?


      When i used 2 granular phases (biomass, sand) without species transport, there is no problem with convergence


      But when i switch to species transport with 2 granular phases (one is a mixture of 2 species and the other is sand), then the simulations dont converge. then i turned off the granular option for mixture and everything worked perfectly. Please explain this problem


      Besides, I have another problem. 
      "THE TEMPERATURE IS LIMITED TO 270 IN 1901 CELLS ON ZONE 2 IN DOMAIN 3..." How can i address this issue except using the limits option in controls bar..


      Thank you.

      Yes you can model that. The warning might be due to the fact that there is a rapid and large temperature drop due to phase change, reactions, wrong boundaries., etc.
