I already tried with high refined mesh, but it also doesn&rsquo;t work. I went back to low mesh to improve calculation time, because some simulations were really really long (for example after patching temperature and\/or species, the calculation time is extremly high, more than 20min for 1 iteration).&lt;\/p&gt;&lt;p&gt;I understand that the problem might be blowoff limit of the flame, but the burner that I&rsquo;m studying have a &lsquo;simple&rsquo; geometry, without swirl\/pre-heanting or other thing to stabilize the flame. A worker already did a thesis with this burner and succeed to obtain good stabilization with &lsquo;real&rsquo; experiment. Hence, I think the problem might comes from my model&hellip;&lt;\/p&gt;&lt;p&gt;I succeed to modelize using the Non-Premixed combustion, with Steady-Diffusion Flamelet + prompt and thermal NOx =&gt; perfect results.&lt;\/p&gt;&lt;p&gt;My problem is that for the future, I would like to add ammonia in my model, and I&rsquo;ll need fuel NOx calculations, which is impossible with Non-Premixed model without activating Discrate Phase, not suited for my case (I think).&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Hence, the EDC model seems to be the best solution in my case, since this model can calculate NOx model with the mechanism imported.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Do you have any advice please ?
