[Gmsh] How to work with arrays?

[Ruth Vazquez Sabariego]

Dear Aleksejs,
The problem is the indexing. You should start at 0.

For i In {0:n-1}
   ss1[i] = ...
   ss2[i] = ...
   ss3[i] = …
EndFor


Otherwise, the first element of the array won’t be correct.
From your error msg, seems to be 0.

Regards,
Ruth

Dear Gmsh,
I am trying to make a complicated surface loop

surfloop = newreg;  Surface Loop(surfloop_air) = {ss1[], ss2[], ss3[], ss4[], s1, s2, s3, s4, s5};

where s* are Plane Surfaces and ss* are arrays of plane surfaces. I generate my surface arrays in a loop

For i In {1:n}
   ss1[i] = ...
   ss2[i] = ...
   ss3[i] = ...
EndFor

I notice that this works if only ss1 is generated inside the loop, as then the index GMSH assigns to it is continuous. Otherwise I get error "Unknown surface 0". However, I can plot any one entry of any array, e.g. ss2[18], and I would see what I expect, so the arrays are correct.

Could you please explain to me, what is the correct way to pass all entries of an array?

Best regards,
Aleksejs
