Problems with the use of PIC to simulate chemical reactions

Dear Developer:
I am calculating topics related to biomass pyrolysis and chemical looping gasification, but in my case, after a short period of normal calculation, the following errors always appear. The code locates to the line of constant density and variable size, but I have not checked where the problem is.I tried to remove the oxygen carrier particles and only injected biomass particles, and this situation still occurred.I really hope to get your help :smiling_face_with_tear:!!Thanks a lot!! Please find the case in attached file
