tutorial improvements
from Takuya OSHIMA, oshima@eng.niigata-u.ac.jp, on the mailing-list:
Hi,
We are doing some detailed review of the tutorial files (t1.geo - t9.geo that come with Gmsh 2.4.2) as a process of creating teaching materials for our FE code that uses Gmsh as preprocessing front end. In the process, at the stage of the review until t3.geo, we came to have the following comments (we hope we are not nitpicking). What do you think?
Thanks, Takuya
[t1.geo] Line 62 "specifying their orientation": it might be better if we have an explanation that this applies only for lines and surfaces, and have an example in one of the following physical entity definitions so that one can see how to specify the orientation.
[t2.geo] Overall, one may hardly be able to follow the tutorial since there is little explanation about which entities Points 8, 12, 16, 7, Lines 102-105, etc. are referring to (and which exact process generated the entities). If the entity numbers are to be obtained by saving unrolled geometry as explained at the bottom of t2.geo, the explanation might be better to come at the top of the file and to be clearly stated as such. Lines 32-33 "a list": it might be better if it is clearly stated that the list is referring to tmp[] (obvious for programmers, but not for non-programmers).
[t3.geo] Line 40 "news": the special meaning of the variable may be worth being mentioned. Lines 76-77 "`Tools->Options->Save as defaults' button": there does not seem to be such a button on the GUI?
