Dear CFD community,

I have a question regarding the specification/implementation of the marker elements in the SU2 text file.
According to the wiki:

The node index numbers are the indices used for specifying the connectivity information for elements....
For each boundary, the connectivity information is given which is based off of the same node indices given above.
With that in mind I implemented a converter to SVG and found some strange boundary shapes in some SU2-files in the Master branch of the TestCases repository. When I do not use the supplied index in the last column for the nodes, but instead use their position in the list as index, I get a shape as expected. I did not dig into the source code of SU2_CFD but maybe this should be clarified before relying on results for these that SU2-files.

Any ideas ?
