Hi All,

I am trying to mesh a cylindrical vessel that has a hemispherical indent at one end. I am trying to use a structured mesh. When I do so I always have a number of cells in the area surrounding the hemispherical section which have a skewness of 1.

Does anyone have any ideas how I may be able to reduce the skewness without increasing the cell numbers to significantly.

Thanks Shane

Have you tried to decompose the geometry? If not, try out this so that it is possible to get the spherical volume to represent a logical cube. Go through gambit manuals-Volume splitting/Meshing.

For the whole spherical geometry, the best way is divide sphere into 8 equal sub-domain. For each domain uses tri-primitive type and cooper scheme.
