STAT_NON_LINE Algorithme contraintes planes (ou 1D): Deborst

Hello,

I have a STAT_NON_LINE model with same *.comm and two nearly same meshes.

But the solver works different:

mesh 1: 1D Elements are the same, 2D elements 99,9%

..
...
....
Liste des comportements
Affecté sur 427 éléments
  Relation                             : ELAS_POUTRE_GR
  Déformation                          : GROT_GDEP
  Algorithme contraintes planes (ou 1D): Deborst
  Nombre total de variables internes   : 7

         V3 : GR3
         V4 : DB1
         V5 : DB2
         V6 : DB3
         V7 : DB4

  Nombre total de variables internes   : 2
         V1 : EPSPEQ
         V2 : INDIPLAS

and

mesh 2: 1D Elements are the same, 2D elements 99,9%  + same tria3 and quad4 added

..

How can I control the solver  behavior ".. Algorithme contraintes planes (ou 1D): Deborst.."? Where can I set ALGO_1D = 'DEBORST'? About information I'm happy.

Thanks and greeting Markus

Hello,

problem located. It was a 2D element in the 1D group in the big modell mesh.

Thanks and greeting Markus
