Chemical Reaction Maximum Step for Combustion CFD-STARCCM
Hello, I need some help for the combustion simulation
I used StarCCM to do simulation, and usually for the chemical reaction, thermo and transport I use GRI 3.0 Mechanism (more than 300 reaction steps). Actually I got good result when I use GRI 3.0 mech, even though when I check the OH mole fraction, it show little bit long concentration region, but the temperature looks fine so I want to test using another chemical reaction and right now I want to use USC version II (more than 700 reaction steps). when I tried to import it to StarCCM it just loading and take so much time, I think it is not normal. So is there any limit for the chemical reaction steps for StarCCM? fyi, I usually use 30 cores for load the GRI and it is quite fast I really appreciate if there is somebody can help me to overcome this problem |
There shouldn't be any limit...
Reading the reactions is simply reading a text file, using a million cores will not speed this up. |
