1D element forces at endA and endB

Hi,

Is it possible to visualize (vector plot) un-averaged 1D element (CBAR, CBEAM) forces/moments at either end of the element (endA and endB)?

It looks that Hyperview supports only averaged results. Even the free body diagrams for bar elements look the same (opposite sign) regardless which node is selected.

Thanks,

MS

    Hi,

    DId you try setting GLOBAL_OUTPUT_REQUEST for GPFORCE?

    it will output forces at grid points

    No, the model has been already run in Nastran and I only have access to output, xdb.

    I can easily extract results (force, stress, etc.) at either bar element end in Patran, however, it seems this is not possible to replicate in Hyperview.

    When you plot vector results, set 'Resolved In' as 'analysis system' => will not transform results

    Yes, the results, average at bar centroid, will be transformed to a selected coordinate system. However, I still won't know what are the component results at both bar ends.

    It's not only a vector plot or report/query table, even a contour plot for a single bar element highlights it in one colour, without pointing where is the max and min. 

     

    I have just found in the help manual the supported elements types and their corresponding component mapping information, some are listed as average of End-A and End-B, or GA and GB. So I'm pretty much convinced the individual results at bar ends are not available... but I hoped they can be somehow (through a script) extracted.
