    element volume: meaning?

    Manuel Coelho
      Hi all

      When viewing stress results, on the top left of the screen we have some data related to the study and the model. One of the displayed itens is the "Element Volume".

      Can any one explain me the meaning of this? What values should we get here, if it's related to results quality?

      Regards

          OK! Just find out it's related to the amount of elements displayed.
          For example, adjusting ISO Cliping to the left, we will have 100% of element volume (all elements are displayed). If we select to the rigth, element volume will display the ammount of material with stress values above the selected value of the ISO cliping ruler.

          Didn´t find any information about this item, in the CW docs.

          Regards

            Hi Manuel. That's very nice. Try reversing the iso surface and the volume displayed reverses accordingly.

              It seems that "Element Volume" is not really a volume at all, but rather the percentage QUANTITY of the total number of elements in your mesh.  So it is really only representing the volume of your total model that is at or above the iso-clipping level if you have a consistent mesh across you entire model.

               

              Generally we've found that the areas that were actually interested in, are where we usually apply mesh controls, where the element size is different and hence the larger number of elements in that area skews the "element volume" higher than that actual volume of your model that is above the iso-clipping level.

               

              I think this should really be renames element percentage or something of that sorts becasue it's current title misrepresent what it appears to be measuring.  Or better yet is should provide what perventage of the total volume is actaully above the iso clipping level.

                  Agreed.  It's misleading.  It would be much more helpful to display the material volume above a certain stress than the percentage of elements.  As you said, it's common to apply mesh controls in areas of high stress and therefore the percentange number is not really helpful at all (in my opinion.)
