shapetoCell in topoSet
 

Hi all,

i want to use topoSet to definte a triangular prism. There is a tool called shapeToCell. But there is no further information about how to use it. Can anyone show me how can i deinite this region? Or there are some other choices i can use? Thank you in forward.

Hi,

Have you looked at the "master" topoSetDict?

https://github.com/OpenFOAM/OpenFOAM...et/topoSetDict

So I should think that for your prism cells, you simply choose the type as prism.

Cheers,

Hi Antimony,

thanks for your reply. I have seen this. The problem is that how can i choose this region for a prism. I may need to give the vertex of the prism or something?

Best regards

shapeToCell Selects all cells of given cellShape and not all cells within the shape.

shapeToCell not working with proposed syntax
 

Hello,


I'm using OpenFoam 10 and trying to use shapeToCell.


This block on topoSetDict
{
name hexaedros;
type cellSet;
action new;
source shapeToCell;
shape hex;
}
returns this error:
=====================

Created cellSet hexaedros
Applying source shapeToCell
--> FOAM FATAL ERROR:
Illegal cell type cellSet
From function Foam::shapeToCell::shapeToCell(const Foam::polyMesh&, const Foam::dictionary&)
in file sets/cellSources/shapeToCell/shapeToCell.C at line 109.
=====================


If I use the syntax like this (type instead of shape, as suggested in tc/caseDicts/annotated/topoSetDict):
{
name hexaedros;
type cellSet;
action new;
source shapeToCell;
type hex;
}

I get this error:


===================

--> FOAM FATAL ERROR:
Unknown set type hex

Valid set types :

6
(
cellSet
cellZoneSet
faceSet
faceZoneSet
pointSet
pointZoneSet
)
===================

I also checked the shapeToCell.C file and suposedly I should use "type" .


Any clues on what I am doing wrong? Or could it be a bug in the source code?


Thank you!

I could not figure it out in 30 minutes; both topoSet.C and shapeToCell.C ask for the keyword "type", that is why the confusion pops up.. I am curious about the solution..

Thank you Ali Shayegh for the time spent.
I noticed that too and tried to embrace the "type" from shapeToCell.C inside brackets or parenthesis to "restrict its space", but no luck with that too.
