gmshToFoam command
 

Hello,
I am new in OpenFOAM, meshing and CFD, and I am doing my first steps into programming.
The thing is I need to transform the elements generated using Delaunay into gmsh to Voronoi elements. After a long research, I found that maybe gmshToFoam could help me to get a voronoi mesh.
I have a few questions:
1- am I right thinking that gmshToFoam would transform my Delaunay triangle into my Voronoi elements? My model currently has more than 7 MM elements, of course I need to simplified it, but still its wanna be a big model.

2- are you aware of any better method to transform Delaunay into Voronoi?

3- Do you realized where my mistake could be and why can't find the file? Trust me the file location is fine (Home->OpenFoam->mv-2.3.0)

I have been trying with this command but the following mistake appears:
ubuntu@ubuntu:~$ gmshToFoam /Home/OpenFoam/mv-2.3.0/cube.msh

I really appreciate any help you can give me with this.

Thank you very much

cannot find file 'controlDict'
 

The error is here:

Solution: add a file called 'controlDict' in the folder '/home/ubuntu/system'.

To give you a head start, here is an example, but Google yourself to suit your needs
