Hi everyone,

I was trying to adapt the mesh to a higher accuracy on Fluent, however, as I set the mesh to level 4 it give exactly number of cells as the level 2 adaption. Is it normal to have this adaption result? Is there a way to adapt to slightly higher accuracy level (I also tried adapt on top of level 2 adaption, the model freaked out?)?

Check the Cell Refine Level Variable and check if you are constraining the adaption through min. cell volume.n

Hi Array,nI set the min cell volume to 0 everytime I changed level. Is there a standard way of varying the min cell size with different level?nBest regardsnLugia_06n

No. Check cell refine level and if cells are marked to be refined: you cannot have neighbor cells with more than one level of refinement difference.n

How does the software defines more than one level of refinement difference? I adapted all the cells(region 0) only once with the same min refinement level and min cell volume. Would be possibly be a problem?n

The level is how many times you can adapt a cell, not how many times it will be adapted when you press the Adapt button. n
