Vladimír already answered, let me just add some remarks.

Historically, the "long syntax" (material_#) was used but then we added the "short syntax" (materials) so that the problem description files were more concise. The same holds for other keywords.

I am now using the short syntax exclusively, and would agree removing the long syntax, if it comes to discussion.

Also, the examples seem to favour the long syntax, and there are very few interactive ones, see also [1].

Hi Matthew,

you can use the long syntax or the short syntax. See http://sfepy.org/doc-devel/users_guide.html#problem-description-file.

Long syntax:

material_1 = {'name': 'mat1', ...} material_2 = {'name': 'mat2', ...}

Short syntax:

materials = { 'mat1': ..., 'mat2': .... }

There is no other difference.

Regards Vladimir

Can someone tell me the difference between the dicts materials and material_1, material_2? I see references to all those in the examples, but I'm not sure what the differences are.
