Hi..I am trying to use topoSet for creating a porous cell zone named v_porous. I converted fluent mesh into openfoam mesh. my topoSetDict file looks like this -

/*--------------------------------*- C++ -*----------------------------------*\
| ========= | |
| \\ / F ield | OpenFOAM: The Open Source CFD Toolbox |
| \\ / O peration | Version: 2.2.1 |
| \\ / A nd | Web: www.OpenFOAM.org |
| \\/ M anipulation | |
\*---------------------------------------------------------------------------*/
FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system";
object topoSetDict;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

actions
(

// Load initial cellSet
{
name v_porous;
type cellSet;
action new;


source boxToCell;
sourceInfo
boxes
{
p1 (2.6 1.5 0.3);
p2 (3.2 2.1 0.5);
}

}
// Get all faces in cellSet
{
name v_porous;
type cellZoneSet;
action new;
source setToCellZone;
sourceInfo
{
set v_porous; // name of cellSet
}
}

);


// ************************************************** *********************** //

However when I do topoSet, I get following error:
------------------------------------------------------------------------------------
Create time

Create polyMesh for time = 0

Reading topoSetDict

Time = 0
mesh not changed.
Created cellZoneSet v_porous
Applying source setToCellZone
Adding all cells from cellSet v_porous ...


--> FOAM FATAL IO ERROR:
cannot find file

file: /Desktop/Trial/constant/polyMesh/sets/v_porous at line 0.

From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting
----------------------------------------------------------------------------------

Am I missing some step in between? A file called v_porous should be there in sets inside polyMesh folder. How is it generated?

Request help. I am new to OpneFoam. Thanks in advance.

Just a guess: Try to name your cellSet and cellZoneSet differently.

Thanks TobM. That doesn't seem to work.
Same error again.

Hi,

You are using quite interesting syntax to define boxToCell source.

source boxToCell;	
sourceInfo
boxes
{
p1 (2.6 1.5 0.3);
p2 (3.2 2.1 0.5);
}

Both 2.4.0 and 3.0.x suggest the following:

source boxToCell;
sourceInfo
{
    box   (0 0 0) (1 1 1);
    //boxes   ((0 0 0) (1 1 1) (10 10 10)(11 11 11));
}

And since you have only two points, you need box variant.

Hi Alexey
Your suggestion did the trick! I guess I picked up syntax from some older tutorial and messed it up. Thanks a lot!
