Question about the data structure of Mesh file
 

I generate a single block 3D mesh (hexa), then I output the mesh and the boudnary conditions;

Then I check the *.vrt file and found that the ordering of vertex is mussy, i mean it is not in a structured way (like first scan in one direction, then the other two directions)

Even it works well for STAR-CD, because it may not care about ...

But I wondering how can i get a good order of vertex?

I notices this seems to connected to the ordering of connectors and domains creation.

thank you for your help.

creorder may do what you want.

sorry, what do you mean 'creorder'

It is a StarCD command which reorders the numbering scheme.

At the StarCD command line, enter "help creorder".
