why does increasing mesh ruins my simulation ?

Hello, can you tell me why when I increase mesh my steady fluent simulation diverges ( continuity 1e10) and gives very weird results?
I noticed that only when the mesh has a very low number of elements the simulation converges ( continuity 1e-7)and it gives a rational result. it is a 2d convergent-divergent nozzle with ideal airflow (inviscid model) inlet gauge total pressure is 101325 p initial gauge pressure is 90000 p outlet absolute pressure is 80000 p Attachment 87494 |
