problem in meshing
 

hello everybody,
i have 2 cylinders: the first is the big one and it isvertical and the other is small and tangent to the first.
i splited the 2 volumes, than meshed the big one with hexa. When i am trying to mesh the small one (with tetra) a message appears:
check the skewness of your face meshes and make suree the mesh face sizes are not too large in areas of small gaps.
what should i do?
thanks for ure help

you need to change your mesh count/spacing along the edge of the cylinder..you need a larger number. your mesh is too coarse
