Default stability of scheme due to skewness/aspect ratio

hi,

i would like to know how the skewness or aspect ratio of a structured grid can affect the stability of a FVM scheme.

For instance, near the boundary, the cells are usually "elongated" rectangles ie they've high aspect ratio. will this affect the stability if their ratio are too high?

So is the best type of cells almost squarish ie non skew and aspect ratio of 1?

thanks
