I wish to simulate a combustion in Fluent 13.0 with the "gri 3.0"-mechanism. After importing it in chemkin format (with the appropriate thermo.dat) and setting to pdf transport model, there appears a message "Maximum of 50 solved species allowed. Use Dimension Reduction instead." (gri 3.0 has 53 spesies). I have tried to reduce the number of spesies to 50 using the "Dimension Reduction" option (choosing out varios three spesies from the list "i wish not to take part"), but it doesn't work, nevertheless. In the 'Spesies Model' dialog box the number of volumetric spesies can be seen under "reduced-dimension-mixture", which remains 53 (in spite of using the dimension reduction option).
Do anybody know how to use a 50-species (e.g. reduced) version of GRI-Mech 3.0 in Fluent???


Thanks, buxtsued
