Meshing areas

[Luca97]

Hello, I need to mesh a certain number of shells. Before that I mesh, if I perform an ALIST command I obtain:

LIST ALL SELECTED AREAS.
NUMBER LOOP LINES AREA ELEM SIZE #NODES #ELEM MAT REAL TYP ESYS SECN
2 1 73342 73343 73344 0 N/A 0.000 0 0 5 2 2 0 0
15 1 73378 73379 303 0 N/A 0.000 0 0 5 15 2 0 0
16 1 73380 73381 73382 0 N/A 0.000 0 0 5 16 2 0 0
18 1 73386 73387 73388 0 N/A 0.000 0 0 5 18 2 0 0
... and so on...

I've used the REAL constants to define the thickness of each shell. So I didn't define a section.

If I perform an AMESH command on all the areas I obtain this ALIST:

LIST ALL SELECTED AREAS.
NUMBER LOOP LINES AREA ELEM SIZE #NODES #ELEM MAT REAL TYP ESYS SECN
2 1 73342 73343 73344 0 0.2355 0.000 -1 1 5 2 2 0 -1
15 1 73378 73379 303 0 15.05 0.000 -1 1 5 15 2 0 -1
16 1 73380 73381 73382 0 0.2355 0.000 -1 1 5 16 2 0 -1
18 1 73386 73387 73388 0 4.129 0.000 -1 1 5 18 2 0 -1



I've receive also this errors, when I perform CHECK command:

Shell element n.tot reference section 1 (always) which is not a shell section, it will be associated with real costant n.tot



I think that it doesn't mesh my shells... But I don't know why... I miss something? I'm using SHELL181 elements.

*of course is not an error but a warning, when I perform CHECK.

I think that there are some shells that are not meshed because in the graphics I've some areas that are still purple instead of cyan... ??
