Due to the size of the mechanism that I&#8217;m using, I need to use the FGM model to speed up this study. My problem with using the FGM model is its treatment of the laminar flame speed when none of the fuel species native to the software is included in the tabulation. Even though I&#8217;m using pure ammonia fuel, the model uses methane characteristics to calculate the flame speed, which is a massive discrepancy. Is there anyway that I can tell the model to use ammonia&#8217;s characteristics for the flame speed calculations instead of me manually inputting those values?&lt;\/p&gt;&lt;p&gt;Thanks in advance,&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392416","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hey, all:I&#039;m wanting to conduct ammonia combustion simulations to see if I can match the NOx trends that two papers reported that I&#039;m currently following.
