This is a question about syntax between the different versions of OpenFoam.
In the openFoam.com version, the surfaceFeatureExtractDict looks like this:


surfaceFeatureExtractDict
main.stl {
extractionMethod extractFromSurface;
extractFromSurfaceCoeffs {
includedAngle 150;}
}
orifice.stl {
extractionMethod extractFromSurface;
extractFromSurfaceCoeffs {
includedAngle 120;}
}


Whereas, the way I have been showing it in the openFoam.org version is:


surfaceFeaturesDict
surfaces (
"main.stl"
"orifice.stl"
);
includedAngle 150;


Question: in the latter version, the .stl files are grouped together, with one overall includedAngle number. If for some reason, I wanted to have different includedAngles, how would I list them separately with different angles, as is done in the openFoam.com case?

Hello Alan,

A simple tip which can be very useful: in the OpenFOAM installation directory, have a look at the etc/caseDicts/annotated/ directory. It contains annotated dictionaries allowing you to see the different functionalities available in a specific dict file. I don't know if it is really exhaustive but this is usually a very good starting point for a lot of utilities.

This directory exists for both ESI/OpenCFD and foundation branches. For instance about surfaceFeatureExtract/surfaceFeatures :

• OpenFOAM-8: surfaceFeaturesDict
• OpenFOAM-v2012: surfaceFeatureExtractDict

Have fun!
