6. Examples#
for GIBI: \(A\) and \(B\) are named points.
So, in the Aster mesh, we find GROUP_NO with names \(A\) and \(B\)
for GIBI: \(\mathit{AB}\), \(\mathit{CARRE}\), \(\mathit{C1}\),…, \(\mathit{C4}\) are named meshes.
We therefore find in the Aster mesh some GROUP_MA of names: \(\mathit{AB}\), \(\mathit{CARRE}\), \(\mathit{C1}\),…, \(\mathit{C4}\)
Note:
The interface only writes possibly identical meshes once (which sometimes happens with the « AND » operator in GIBI). This means that the names of the meshes \({M}_{j}\) may have a « hole numbering ». There is no need to worry about it.
The orientation of the meshes is that given by GIBI. This may be important for certain changes: pressure,…
You should be aware of the fact that the mesh operators in GIBI orient the elements (with rules specified in the documentation). Some items may be « returned » compared to others. Another command set GIBI could, for example, have generated the mesh:
6.1. Note about order POIN from GIBI#
This command may produce results of different types:
if this order allows you to recover a single point,
for example:
PA = toto POIN PROC A;
or
PA = toto POIN INITIAL;
so \(\mathit{PA}\) is a GIBI point named.
For*Aster*, we will have a GROUP_NO with the name \(\mathit{PA}\) that contains only one node.
if this command allows you to recover several points:
for example:
PA = toto POIN DROIT A B 1.0D-2;
so \(\mathit{PA}\) is a GIBI mesh named:
This mesh consists of POI1 meshes.
For*Aster*, we will have a GROUP_MA with the name \(\mathit{PA}\) that contains several POI1. To use this object as GROUP_NO, you’ll need to use the CREA_GROUP_NO keyword factor from the DEFI_GROUP command.
