Hello Berbiche, you need to create a node and a 0D element, so the node does not remain orphan. Once you have created the node in Salome Mesh module with the "Add Node" feature in Modification/Add/Node, you have two options to create the 0D element:
- use the "Add 0D element" feature in Modification/Add/0D Element
- use a CREA_MAILLAGE command in your .comm file, with the "CREA_POI1" keyword (you need to create a group of nodes containing only the node you created in Salome beforehands). It will create an element group with the same name than the node group.
If you cannot apply your loading because of this single node, I suggest that you try to create a group of nodes in Salome with the "Create Group" in Mesh/Create Group, before you start using code_aster or asterstudy, and use the second option to create your 0D element.
