Extract element volume

Recommended Posts

Dear all,


I need to carry out some calculations and for that, I need to know the volume of each element separately.


Is there an easy way I can extract these values from hypermesh or even hyperview?

hm_getvalue elems id=<Elem-ID> dataname=volume


How would I apply this command line? Scripting?

You can execute this command directly within command window (below of graphical area) or write it into a TCL script.


I applied this command but it seems to extract the volume from single elements. I have a component with 1 million + elements so what I need is to extract the volume of every element and save it into a file.

Is there a way to adapt this command to automatically do it? Or is there another way?

Thank you!


Btw, I also found that you can easily plot and extract it from Hyperview by using derived results

Hey, friend. I'm also trying to extract the volume of all elements in a model. Could you tell me how did you make it in Hyperview? T

You could perform this in HV using Result Math. You need to load your result files and choose 'Advance' in Math Template.



Then, go to 'Derived Results' tab, and create a new expression, giving it a name.

This lets you created derived expressions based on some results, math, etc.

You will edit the expression using the command' Volume()' and save it.

After that, you will have a new result with the name you gave. Contour this result in 'Contour' tab and then use query to request all the elements, then export it as a CSV.




In HM you can use the command line mentioned in above replies with a few changes.


#user selects elements and stores in a variable elems_list

*createmarkpanel elems 1 "select elements to calculate volume from:"

set elems_list [hm_getmark elems 1]

*clearmark elem 1


$retrieves the volume of all the elements stored in mark 1

eval "*createmark elems 1 $elems_list"

set volume_list [hm_getvalue elems mark=1 dataname=volume] 

*clearmark elems 1


#writes the data to a CSV file

set fo [open "dir/filename.csv" w]  ; ### CHANGE THIS ###

foreach elemo $elems_list volo $volume_list {

     puts $fo "$elemo $volo"


close $fo
