Design Study constraint keeps changing units from in to lb.

Joseph Eimer Feb 26, 2013 4:13 PM

I'm conducting an optimization for the attached loaded beam. The profile of the loaded beam is defined via an equation. I'm trying to control the heigh of the beam by adding a dimension sensor and placing a "is less than" constraint on the dimension sensor. For some reason the constraint shows up as having units `lb'. Does anyone know why this is happening and how I might constrain this thickness succesfully?

Thanks!

Hi Jospeh,
You can resolve this issue by measuring the distance between the two end-vertices rather than the length of the line. Give it a try and run the simulation and your issue should be resolved.

  Hi Irfan,
  
  Thanks for the response! I must be misunderstanding your recomendation. I've included a screen shot showing my original Dimension sensor in the left-hand tree and the new measurement sensor. This new measurement sensor was defined by selecting the end points of the the 3.18" line (also visible in the screen shot). Both of these sensors are correctly showing 3.18" in the tree, However both are still showing units of `lb' in the Constraints section of the design study. I'm probably just misunderstaning your recommendation.Could you give more specific details?
  
  Thank you!
  
  Best regards,

    Dont care about the units/ you can type them in manually. Once you run the design study, you should get the right results.
