Meshing areas

Meshing areas

Meshing areas

(OP)
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.

 

RE: Meshing areas

(OP)
*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... ??
