Transfer GEOM groups on mesh was created by ishmael
A very basic question: once I create a group on geometry (example: a surface in order to assign a pressure on Code Aster), once I have meshed the geometry I create manually the same group, this time on mesh entities by creating a mesh group on geomery, then selecting the geometry group.
This seem to work and is not very time consuming,but I'm not sure is the correct approach: from what I understand from other forum posts, it should'nt be necessary, and the groups on geometry should be automatically transferred on the mesh entities.
However, I'm not able to see the automatically created groups on mesh.When are them supposed to "appear"?
Am I doing something wrong?

Thanks!

Dear Ishmael,

you approach is 100% correct! But thanks to the integration between Salome and Aster (=Salome-Meca), you don't need to create the mesh groups when use one of the wizards. In Eficas, you can directly select the GEOM groups:
Let's suppose that you want to define a group of elements in Eficas (keyword GROUP_MA)
- activate Salome & select a geom group (in the tree, it is much simpler)
- go back to Eficas, and in the GROUP_MA "editor", press the "left arrow" button and it will add the group to the GROUP_MA list
- when you save the comm file in eficas, you will be asked to Update a mesh: this is actually what creates the mesh groups from the geom groups

Hope it it usefull to you

Joël

Hi Joel, thank you so much for the reply: I didn't know at all about this feature of the Code_Aster integration, it's very helpful, and now I understand the meaning of the "update mesh" prompt B)

Thanks :-)
