Dear gmsh-ers, Two beginner questions: 1. I am wondering about the order in which various sections appear in the output file. The documentation seems to imply that PhysicalNames follows the Elements section, however this is the other way round when looking at output files. Is the order then always: MeshFormat, Nodes, PhysicalNames, Elements, etc. or is it free (which makes reading the file a bit more hassle). 2. I experimented a bit with generating multiple physical tags and saw that in this case multiple entries of the specific elements are generated in the output file (not what I would like). I was also a bit puzzled by the order in which these duplicates (with different tag) appear. In the case of 2 tags, the entries were listed reversed wrt their definition in the geo file. If the range of tags that you use is similar then there is no way to distinguish between different physical properties (e.g. tag1 = material type, tag2=source strength, etc.). I guess I need to use a specific range of tags to identify what they mean. What puzzles me is why the file format allows for 'number-of-tags' if this can not be influenced? Is there perhaps another way to force multiple tags on a single output line? Many thanks, Danny Lathouwers
