Thanks

Hello,

The global node number can be retrieved from the local node number thanks to the attribute array KNOLG of a bief_mesh structure:
global_node_number = MESH%KNOLG%I(local_node_number)
The array KNOLG is assigned in the hermes subroutine get_mesh_l2g_numbering.f

Reciprocally, the local node number can be obtained by the call to the bief function global_to_local.f:
local_node_number = GLOBAL_TO_LOCAL_POINT(global_node_number,MESH)
It returns 0 if the point is not in the subdomain.

Regards,
Laurent
