Create your own chemical scheme
The following procedure is valid for Meso-NH versions since MASDEV4_9_0
STEP 1: write your chemical scheme
in a specified format (*.chf) like this one: ReLACS-mix-reac.chf
Edit this chf file and make the necessary changes.
STEP 2: create the fortran source
with the awk program m10.awk
Usage: "m10.awk ReLACS-mix-reac.chf"
STEP 3: compile your chemical scheme
Change the name of the chemical scheme to BASIC.f90
Create your user library (see the A-INSTALL file) and compile.
