Reading Vertices from another file

is it possible to read the vertices in BlockMeshDict from another file?

I saw a blockMeshDict that the vertices were referenced in this manner

Code:

vertices

(

    ( $x0 $y0 $z0 )

    ( $x1 $y0 $z0 )

    ( $x1 $y1 $z0 )

    ( $x0 $y1 $z0 )

    ( $x0 $y0 $z1 )

    ( $x1 $y0 $z1 )

    ( $x1 $y1 $z1 )

    ( $x0 $y1 $z1 )

    ( $x2 $y0 $z0 )

    ( $x3 $y0 $z0 )

    ( $x3 $y1 $z0 )

    ( $x2 $y1 $z0 )

    ( $x2 $y0 $z1 )

    ( $x3 $y0 $z1 )

    ( $x3 $y1 $z1 )

    ( $x2 $y1 $z1 )    

);

how does it work? is there anywhere I can read on how to do this?

thank you.

Hi,

your sample snippet uses variables for parametrization of the blockMeshDict file, have a look at
https://sites.google.com/site/snappy.../blockmeshdict for further information.

As far as I know it's not possible to read vertices from other files (beside including another dict and using the variables defined in there). You may use any scripting or programming language to create a blockMeshDict though. This script/program could read the vertices, process them and write an appropriate blockMeshDict. Have a look at http://www.cfd-online.com/Forums/ope...ctions-m4.html for a sample using the Python scripting language (needs to be extended to write the whole blockMeshDict).

Have fun!
