Dear all,


I am using topoSet to create a region inside the mesh. The original mesh is obtained from stl file which is meshed using snappyHexMesh (The stl file mesh is similar to sphere shape).



I wanted to create a spherical region inside this stl file for which I am using topoSet. I have created cellSet, cellZoneSet for the spherical region and also deleted it from stl mesh file using surfaceToCell.



The topoSet runs well in terminal, but does not create a cellZone for the spherical region. But creates a cellZone for the stl file. What am I missing in topoSet?


I have checked in constant/polyMesh/cellZones



Below is the the topoSet file.


actions
(

// gland
{
name glandCellSet;
type cellSet;
action new;
source surfaceToCell;
sourceInfo
{
file "./constant/triSurface/mesh2.stl";
outsidePoints ((100 70 10));
includeCut true;
includeInside true;
includeOutside false;
nearDistance -0.05;
curvature 0.9;
useSurfaceOrientation false;
}
}


// tumor
{
name tumorCellSet;
type cellSet;
action new;
source sphereToCell;
sourceInfo
{
centre (100 100 30);
radius 1;
}
}

// set tumor cell zone from cell set
{
name tumor;
type cellZoneSet;
action new;
source setToCellZone;
sourceInfo
{
set tumorCellSet;
}
}




// gland-tumor

{
name glandCellSet;
type cellSet;
action delete;
source sphereToCell;
sourceInfo
{
centre (100 100 30);
radius 1;
}
}

// set gland cell zone from cell set
{
name gland;
type cellZoneSet;
action new;
source setToCellZone;
sourceInfo
{
set glandCellSet;
}
}

);




CellZone region which shows 0 cellLabels for the spherical Region "tumor"


2
(
tumor
{
type cellZone;
cellLabels 0();
}







I have attached the link for the stl file.

Any leads will be appreciated.
