Re: "error message:negative volumes exist"
Dear Hash:
Negative volume means that some cell on your grid are overlapped and/or disattached. Means improper connectivity. You can eliminate this problem using Iso-value adaption. However if you want to see these cells use adaption->iso-value->mark. Regards |

hi i faced the same problem when tried to mesh with a larger mesh size than a small dimension in geometry. i remshed and problem is loved. but as MEHDI said Iso-value adaptation, what fluent do to the mesh to remove -ve volumes. isnt remeshing is more appropirate. because i got only 1 -ve vloume and funny thing i can not see it. so i remshed :)
