Soot Flags and Inputs

• In the GNUmakefile, specify USE_SOOT = TRUE and NUM_SOOT_MOMENTS = N where N is the number of moments to be used in the solution, either 3 or 6.

• Depending on the gas phase solver, soot solving functionality can be turned on in the input file using pelec.add_soot_src = 1 or peleLM.do_soot_solve = 1.

• The chemistry model specified with Chemistry_model = in GNUmakefile must contain the PAH inception species, as well as H2, H, OH, H2O, CO, C2H2, and O2.

• A PAH inception species must be provided in the input file using soot.incept_pah =. Currently, only one of three inputs are accepted: A2, A3, or A4; which correspond to naphthalene (C10H8), phenathrene (C14H10), or pyrene (C16H10).

  • If the inception species is named something other than A# in the chemistry model, a different name can be specified using soot.pah_name =. However, soot.incept_pah must be set to A2, A3, or A4.
