Really small cells
 

Hey all,

I've been trying to creat really small cells but it always fails (collapsing faces, negative volume...) I want to see the boundary layer of water flow over a 1m flat plate for an inlet velocity up to 500m/s. How can I create really small cells without having problems?

Thanks

I'd just create the mesh large - say 100, or 1000 times larger than you want, then change the scaling factor when you write out the problem file.

In prostar4 the vertex definitions are stored in double precision, specifically to help with very small cells. You might try it.
