[GAMBIT] how to delete negative volume?

shahrbanoo · February 4, 2014, 16:18

Hi everybody...
I want to mesh a geometry in Gambit. my mesh is unstructured and tri. but when I mesh this geometry, it has 2 negative volume. and another problem is that we have for example 640 cells that their skewness are more than 0.97. what should I do? and how should I solve this problem. please help me?

skewed elements come essentially from your geometry.
If you are refering to the same geometry mentionned here (http://www.cfd-online.com/Forums/ans...ease-help.html), then you know how to solve this problem
