Hi Folks,

After using an outside meshing tool, I brought the polyMesh folder into openFoam. Then, checkMesh said there was an error with some wrongOrientedFaces.

Now, I'm trying to visualize those faces with surfaceSubset. According to help, the usage for this command is:

surfaceSubset [OPTIONS] <surface file> <output surface file> <surfaceSubsetDict

I could specify the <output surface file> as an stl file, but I am puzzled about the input <surface file>, since it did not originate with an stl file. This would be specified in the system/surfaceSubsetDict file, which I currently have as:

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      surfaceSubsetDict;
}

faces #include "~/cfdaero/civic-bodyonly/constant/polyMesh";

localPoints ();

edges ();

zone ();

addFaceNeighbours no;

invertSelection false;

When I run surfaceSubset, I get this message:

--> FOAM FATAL IO ERROR: 
Istream not OK for reading dictionary 

file: surfaceSubsetDict at line 1.

How do I write the surfaceSubsetDict file, and what is the command to run to create an stl file of the bad faces?

Forgot to check my post before submitting! I meant to show the command I am using:

surfaceSubset wrongOrientedFaces wrongfaces.stl surfaceSubsetDict

But of course this is wrong.
