Hello there,
I’m writing a python converter for some simulation files that come out as unstructured grid .vtu but I keep ending up with extra geometry. Could some one tell me from the following data what the final 2 triangles in the first strip should be? I’m pretty sure the first two should be between indices 0 10 1, and 10 1 11, but I’m pretty sure I get the wrong geometry if I let 19 0 10 be my final triangle in the strip.

If its of any use I’ll attach the .obj ascii that I’m getting out from running my parser on this file.

I should also include the whole .vtu xml file, and perhaps someone will be able to explain perhaps why the first 10 points are repeated?
