The surface to which an element belongs

Akane Ito

Is it possible to obtain the faceId to which a certain element belongs?

Please clarify your question: what tool are you using ? Mechanical, MAPDL, PyMechanical, PyMAPDL?

It's Mechanical.

This should help: https://discuss.ansys.com/discussion/comment/3689#Comment_3689?utm_source=community-search&utm_medium=organic-search&utm_term=MeshData You would have to adapt it to get the face in geobody, instead of the entire body, but the principle stays the same.

Dear Pernelle Marone-Hitz
I tried it using the method I was taught, but it didn't work out. If possible, please provide specific instructions.

Pernelle Marone-Hitz

The only thing to add from the previous script is to loop on the faces of the geobody.

element_id  = 25
mesh_data = ExtAPI.DataModel.Project.Model.Analyses[0].MeshData
bodies = ExtAPI.DataModel.Project.Model.Geometry.GetChildren(DataModelObjectCategory.Body, True)
for body in bodies:
    geobody = body.GetGeoBody()
    for face in geobody.Faces:
        mesh_for_face = mesh_data.MeshRegionById(face.Id)
        if element_id in mesh_for_face.ElementIds:
            print('Element ' + str(element_id) + ' is in face : ' + str(face.Id))
