Hi everyone,
i have been simulating my engine model with AMR in converge. I wanna set a Temperature trigger in AMR but i dont know how should i set up the sub-grid criterion. I've tried many times and the sub-grid velocity trigger worked like i expected but in the output amr.out the subgrid_scale temperature in combustion chamber is always the 2.5 which i defined in the sub-grid criterion. I dont really understand that. Dose it mean the amr for Temp-Criterion was all time triggered ? And should i try with higher sub-grid temp criterion?

By the way, dose anybody have experience how we could do a mesh study like convergence analysis or just a study which discuss the relationship of cell count and the accuracy of the results in converge?

I hope someone understand my question and would help me. Thx in advance.
