Question about 'negative cell'
 
Hi,

May I ask what does 'negative cell' mean in Autogrid?

Hi Anna,

It is a so call "negative volume" cell. The cell must have been distorted due to the compression.

Thanks. May I ask what do you mean by 'compression' here?

Hi Anna,

When you have too many mesh within your domain, the domain may not been seem to allocate more mesh and if you insist to increase the cell, this will tend to deform the mesh.
