Hello,

How can I activate adaptive zoning strategy to reduce the computational time?
I read a paper and it says'' temperature and equivalence ratio are used as
variables for grouping cells into zones''.

Regards,
Amin

Adaptive zoning can be found under the combustion modeling tab in studio.
You may also edit the combust.in (shown below) to ativate adaptive zoning. For further details please refer to our user manual available at convergecfd.com/downloads.

# Adaptive zoning
1 adaptive_zone_flag 0=do not use adaptive zoning, 1=use adaptive zoning.
2 adaptive_zone_bin_dim Dimension of adaptive zoning.
5.0 adaptive_zone_bin_temp Temperature bin size (K) for adaptive zoning chemistry.
0.05 adaptive_zone_bin_react_ratio Reaction ratio bin size for adaptive zoning chemistry.
1 adaptive_zone_nox_flag 0=default, 1=improves the accuracy of NOx emissions prediction in the adaptive zoning.
0 adaptive_zone_output_flag 0=no additional output for adaptive zoning chemistry, 1=activate additional output for adaptive zoning chemistry.
0 adaptive_zone_hr_map_flag Use heat release mapping.

Thanks,
