Class 3 Error
There can be a problem of conservation of chemical elements when using CFX RIF. Only the solutions near chemical equilibrium (Chi=0) seem to be affected.
This is due to a bug in the code received from Advance
To work around, you can let the solver ignore the lowest Chi values in the flamelet library by adding the "Skip Over Scalar Dissipation Rate Samples" parameter (Solver Manager/Edit Definition File). Set this such that values of Chi<0.05 are skipped, e.g. for the Flamelet library with 20 samples for Chi:
REACTION: x1 CCC
Reaction Description = 1) C1C4 Tox=288.0 [K] Tfu=288.0 [K] p= 1 [bar]
Option = Flamelet Library
Library File = CCC_cfx5.fll
Materials List = ...
Skip Over Scalar Dissipation Rate Samples = 5 # Set this such that skips samples Chi<0.05
This will give proper balances for chemical elements in the CFD solution. The limitation of this workaround is that chemical equilibrium composition will not be reached, instead composition will be for a (slightly) strained flame.
Not fixed yet.
