Re: REFINE IN ONE DIRECTION
 
CDIRection goes with the command CDIVide.

You establish the cell I, J and K directions with CDIR

Then you use CDIV to split the cells in any given direction

It sounds like you were using CREF on a multi block mesh with different local directions previously. This splits cells based on the existing I,J and K direction of each cell.

If for some reason you wanted to use CREF then you could do

CDIVide RESTructure CREFine

but that merely adds an extra step

PLFACE ON with a PLTY EHID shows you the cell face orientations of the mesh

I believe CREOrder is/was mainly used for reducing the wave front of linear FEA solvers by renumbering the cells such the neighbours had similar cell numbers. I am not sure that it has that many uses other than that

hi. why you don't use the way like "prostar window-->tools--> cell tool--> cell refine" ?

In 326

try the "cmro" command

with the option 1d or vector

then use cmre cset

This should handle all cell type
