How can I judge if my mesh is good? I got:
********************** * ELEMENTS * QUALITY * ********************** * 1 * 0.27 * * 5 * 0.31 * * 26 * 0.36 * * 252 * 0.45 * * others * more than 0.5 ********************** HEXA: 20.000 elements |

you need to see icemhelp manual for quality. there are about 45 parameters for judging mesh quality.
your mesh 'Quality' values given by ICEM depends from element to element. As I see it's a mixture of tetra/prism/hexa elements, you need to check other parameters as well. Again it depends on Solver too. Personally, I'd like to check aspect ratio, orthogonal quality, skewness, mesh expansion factor etc. |

It depends on your solver and the type of elements.
For example, determinant is very important for hexa elements, but not very relevant for tetra elements. You should have a look to the user manual of your solver for more informations. |

It hardly depends on the problem. In some areas good mesh quality isn't very important, but you need to make refinements in areas of interest.
