Error with the unsteady flamelet Model
 
Hallo,

i want to use the unsteady flamelet modell for natural gas combustion. First I tried the GRI 3.0 mechanisem, this work fine. Now I use the san diego mechanisem. The steady flamelet model works, i can initialise the unsteady model, but get the error:

Warning: Species XX not in flamelet-mixture.

but when I create the flamelet-mixture the species is included.
