Is it possible to precisely specify Query points, using coordinates, or planes?

It will be nice of using excel table, and create specific XYZ points.

I need to check the FEA stress, against strain gages.

Thanks,

Boris

    Boris,

    When you ran the analysis, The analysis should have created a folder with the name of the analysis.
    In this folder there should be a file called (Your_Analysis_Name.rpt). Open this file with a text editor.
    In this file you will find the data your are looking for at the end of the file.

    Hope this helps,
    Don Anderson

    Should look something like this:

    Load Set: LoadSet1: PRT0001

    Resultant Load on Model:

    in global X direction: -3.731300e-10

    in global Y direction: 7.743008e-11

    in global Z direction: -2.000000e+03

    Boris,

    You might try using a Simulation Measure over Selected Geometry at Point. (see image below)

    If you create your points as a pattern it will create measures for each of the points you have
    defined in the pattern. (make sure to select the pattern)

    You could then map the measure results in the .rpt file in the analysis directory to an excel file sheet.

      Don,

      Thanks a lot.

      It is very helpful.

      I created the pattern of the points, using CREO.

      After that, I opened a Simulation, and created the measures from the points.

      When simulation is finished, I cannot found .rpt file in the directory, and cannot see any measures results.

      Probably, I missed something. Please, guide me step by step.

      By the way, you already seriously helped me.

      Thanks,

      Boris

      Thanks for the helpful posts. I can successfully do this for a point pattern on the surface of parts, but I need to get stresses inside a part. When I set up a Measure > Point Pattern inside a part, it meshes fine, but I get a fatal error when trying to run it, with messages like this:

      'The measure "Measure1_PNT10" is associated with a point that is not associated with an element.'

      I've also tried making those internal points Hard Points with an AutoGEM control, but that was no help.

      I'm confused on why a Measure that would only be used in the Results stage (like an automated Dynamic Query) would interfere with running the model.

      I've also tried to make a Results Graph following an internal Curve (defined as an AutoGEM Hard Curve). It meshes and the model runs fine, and I can pick the curve in the Results Window Definition > Graph Location step (it actually says "defined"), but it then errors saying there is nothing to show.

      I've also tried inserting a cutting/capping surface inside the part (works fine), and tried to insert another cutting/capping surface perpendicular to the first (to define an internal line), but Results apparently only allows 1 cutting/capping surface. Of course, I can Dynamic Query on that cutting surface, but I don't see any way to pull off a repeated and regular array of data that way.

      How does one get an a regularized set of stress results from inside a part? I'm using Creo 1.0.
