Hi i have meshed an air duct using proam... when i check for grid quality i am getting the following errors:

Error #176 cells found with face warpages greater than the prescribed value.

Error #81 internal angle exceeds prescribed value for some cells.

Error #80 internal FACE angle exceeds prescribed value for some cells.

Error #76 cell faces with very small surface areas found in the model

how do i rectify these errors??could anybody help??

thanks..

i had the same problems (80, 81, 76); reason: cells with triangular cross section which u have just at the axis if u are considering any cylinder; they don't influence the further analysis;
