Access to normalized stresses at stress points

API & Interfaces

Hello everyone,

can someone tell me if there is a way to access the unit stresses at the stress points of a cross-section in RFEM 6 using Python? In the graphical interface, I find them by double-clicking on the cross-section, tab "Stress Points," then "Unit Stresses | FEM."

In the In-App Scripting, there is the property "stress_points." There I can read the geometry, but neither by trying nor under "Insert Object Property" have I found anything related to stresses.

With the API, I have not even found the property "stress_points."

Is access simply not possible with it?

Hi IanKrukow,

welcome to the community!

Regarding to your question this thread might be interessting for you: Read the y,z coordinates of stress points in cross-section - Dlubal Community.

You can also reach the tables about the stress-strain-analysis, for example:

from dlubal.api import rfem

with rfem.Application(port=9000) as rfem_app:
    material: rfem.structure_core.Material= rfem_app.get_object(
        rfem.structure_core.Material(no=1)
    )

    # Example: read unit stresses at all stress points for load combination 1
    lc_obj = rfem.object_id_pb2.ObjectId(
        no=1,
        object_type=rfem.ObjectType.OBJECT_TYPE_LOAD_COMBINATION
    )

    table = rfem_app.get_result_table(
        rfem.results.STRESS_ANALYSIS_STRESSES_ON_MEMBERS_BY_STRESS_POINT_TABLE,
        loading=lc_obj
    )

    print(table.data)

    # pandas DataFrame
    print(table.data.columns.tolist())

I hope that helps.
