Should I use a smaller base level or more levels to get more accuracy?
For CFD, the best option is always to use a smaller base level and fewer levels than
a large base level and lots of levels. This is especially the case when using turbulence
models such as k-ε or when using boundary layer. (see tips on best practice)
For FEA models, cell count is usually the important factor. Try
and use a base level size which gives the lowest cell
count but also gives good surface recovery
