Question about the data structure of Mesh file

harbinyg · March 29, 2011, 10:53

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.

It is a StarCD command which reorders the numbering scheme.

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