In case silane_pyrolysis_pic_3d, no product was found after setting the reaction

Hi everyone,
I found zero product results when simulating biomass pyrolysis based on a DEM model. So I run mfix-24.2.3 in the Linux system to calculate the case of silane _ pyrolysis _ pic _ 3d. This case still did not produce any products after running for 20 seconds.I want to know where the simulation process went wrong.The attachment shows the monitoring results of silane-pyrolysis-pic-3d after running for 20 seconds as an example. Looking forward to your reply very much. Thanks for your help.

Just to be sure, did you build a custom solver as is required for cases with usr_rates code?
