Sensors not available in Linear Dynamic Harmonic Study

Nathan Obermiller Mar 27, 2014 11:09 AM

I am trying to probe my harmonic study results to evaluate the amplification of the model at various points. If I select a Response Graph from the solutions I do not have the option to choose Predefine locations. I added a few workflow sensitive sensors on the assembly but for some reason I do not have an option to select them because Predefined locations is not available. It is difficult to pull the node from the mesh because I adjust the model and re-mesh. Has anyone had this issue, and know why this otion is not active?

Thank you.

version/service pack?
can you post what you're seeing in both the sensor and output interfaces?
is this happening on all models?

  Sorry. 2012 SP5.
  
  Yes, it is happening on all models.
  
  Same thing with a different model.

    so it only works with probe?
    does it work in a nonlinear response plot?

      It does not work with probe either. In order to select the plot, I have to exit out of the menu and open the mesh, then probe my point, then go back to the response graph, scroll through the nodes to select the node, and apply it. Not a very good system when I have 50,000 or 100,000 nodes to sort through. Plus, the scroll bar only lets you go up to about 60,000. If you have a point after 60,000, you have to scroll through the nodes using the keyboard.
      
      I have not tried nonlinear study. I don't believe the Response Graph is an option on the nonlinear problem. I may be wrong.

        sorry for the standard troubleshooting questions, i don't have 2012 sp5.0 available anymore to check
        
        does the probes work in linear?
        
        is this happening on any model, even just a block? if so, please post it and i'll check 2014 sp2.0

        The sensors are shown when probing other plots such as displacement, stress, etc. This is true in the static analysis module, and even in the harmonic study module. However, as shown in the figures I provided, contrary to the Solidworks help description for "Response Graph", I do not even have an option to select "Predefined Locations."
        
        My previous response showed the results for a block.
        
        Are you able to repeat this for SW 2014? Or have the options menus completely changed?
        
        Thanks.

        I found a workaround. You can plot a response graph from the stress, velocity, or acceleration results. This method allows you to select a sensor. But the "Response Graph" results menu option still has that bug.

        don't have a file handy, was hoping you'd post your model so that i could check it in 2014
        
        glad you found that workaround. from your original posting i thought you had already found that option since you mentioned that you were using probe.

Have you set result options to "for specified solution steps" and then chosen "locations for graphs" either as "all tracked data sensors" or "workflow sensative 1"?

This makes the step-by-step results get saved for the sensor. If the results are there then you're able to select the predifined location and actually make the graph.
