Define output spacing

API & Interfaces

Hello,

I would like to export the internal forces of a result member to Excel.
This works quite well so far, but now I want to define the spacing of the output points, for example, outputting the results every 5 mm along the member length. Currently, the spacings depend on the length of the member and are not the same for all members.

Is this possible via the filter function or when retrieving the results?

My code:

filters_Ergebnisstab_1=[
        rfem.results.ResultsFilter(column_id='member_no', filter_expression='1'),
        rfem.results.ResultsFilter(column_id='loading', filter_expression='LC1'),
    ]

results_Ergebnisstab_1: common.Table = rfem_app.get_results(
        results_type=rfem.results.STATIC_ANALYSIS_MEMBERS_INTERNAL_FORCES,
        filters=filters_Ergebnisstab_1,
    )

I am working in RFEM 6.13.0001 and dlubal.api 2.13.1 on Windows

Thank you and best regards
Bert

Hi bert.p,

the returned result data only contains what is calculated by RFEM 6. So, if you want to get results every 5 mm, you have to make sure that the member has a FE node every 5 mm. This can best be achieved by applying a line mesh refinement to the line underlying the member:
LineMeshRefinement — Dlubal API documentation

Hello Clemens,
that is not enough for an output. The FE network nodes are created, but not output. Do I have to set this somewhere else?
I am helping myself now by increasing the "Mesh Settings > Members > Number of divisions for result diagram" for all bars. However, this does not quite achieve the desired effect of a defined uniform result output.
Best regards
Bert

Hi bert.p,

can you provide me a small RFEM example for test purpuses? Then I'll have a deeper look into it.

Thank you.
