Hello all,
Could you please explain me the difference between the two terminologies, 'Mesh Independence Study' and 'Mesh Sensitivity Study'. To me they seem similar. Can somebody explain this please? |

I don't think there is any difference, much like saying what's the difference between a grid and a mesh or a cell and an element, it's just terminology. In lots of cases a mesh independent solution cannot be obtained because either the physics (models) or the available computational resources (very fine meshes required) prohibit a mesh independent solution being obtained. However, one can still, and should, assess the sensitivity of a solution due to the mesh resolution.

I find the terminology mesh independent quite misleading.
Looking close enough at the results, one will always find that the values change when changing the mesh size (provided a non-trivial case). |

Maybe one is related to mesh type (hexa, tetra, mixed) and the other to cell size.
