Identifying nodes of a specific grain from mesh file

[shahul31]

Hello,
Could you please help me with this, I am trying to get nodes of a specific grain of a polycrystal from the corresponding mesh file.

I have generated a polycrystal with 51 no.of grains and meshed it, now I want to get the nodes of grain no 51 which is elset 51 in mesh file, i.e. in .msh file at the end we can see

$Groups
elset
51
1 1
.
.
.
50 1
51 2
$EndGroups

Please correct me if I am wrong, I have identified in the $Elements section that it contains <tag#> of elset and <elt_id_node#> which are the nodes associated with that element of elset.

If this is true, the nodes of grain no 51 I am seeking is it under element type <elt_type> 11 2nd-order tetrahedral elements ??
because the other <elt_type> contains elsets higher than 51!! which is quite confusing.

I've just added:

• -statelset elts, which gives the list of elements of an elset
• -statelset nodenb, which gives the number of nodes of an elset
• -statelset nodes, which gives the list of nodes of an elset

Needs version 4.4.2-26.

That's wonderful, thank you very much.
