I-DEAS unv Netz für Code Saturn cfd - Elementtypen was created by MGolbs
Hallo,
im openFoam habe ich immer Tet4 Elemente für das Medium verwendet. (Wenn ich mich richtig erinnere mussten Wand, Einlass und Auslass Tria3 Elemente sein, die auf den Tet4 lagen - Generierung in Salome. ???)
Wie muss ein Netz für ein Medium mit Wand, Einlass und Auslass in I-DEAS für Code Saturn aufgebaut sein? Welche Gruppen muss ich definieren?
Gruß und Dank Markus

As far as I understand your question: Exactly the same way you built your mesh for OpenFOAM.
Code_Saturne as a minimum needs boundary conditions (face groups) for walls, inlet and outlet.
That means that every exterior face of your mesh must belong to a group.
I-DEAS (unv) or .med can be used with CS (and others)
Tria4 (but not tria10) and hexa8 (but not hexa20) is fine.
Tria10 and hexa20 will be converted down to tria4 and hexa8 if used.
Regards,
Claus

Hello Claus,
thanks for the replay. The name of the faces I define for example in Salome or an other FEM Pre-Prozessor and the I export in *.unv or *.med. Is it important use only 8 character's or can it be more character's?
In Sature I define wall, inlet and outlet with this name of face groups?
Greeting Markus

I would assume that using more than 8 characters will lead to problems, so stay with max. 8.
Yes, under 'Boundary conditions' in the Saturne GUI you enter the names of the face groups under 'Selection criteria' and assign a boundary condition under 'Nature'

Hello Claus,
thanks for the informations. I will test my first Code-Saturn modell in the next days.
