Using Matrix Browser to select very specific elements

awe901

Good Afternoon.

I am actually using Hypermesh 2019; there was no option for hypermesh 2019 in the drop down above.

I am attempting to obtain element information on my model on very specific intervals (see attached image for clarity). I have a model that I need to extract individual element volume bounded by the region 0 ≤ x ≤ 3 and 5 ≤ z ≤ 15 and the whole domain of the y-axis. The mesh that I used to generate elements already has perfectly smooth surfaces along the boundaries of this location, so I don't have to worry about only "partially" selecting an element. In generally, what I am attempting to do is to obtain two characteristic pieces of information about every element on the interval listed above. I need the Element ID, I need the Element Volume, and I need the heat flux through that element. Hypermesh can't give me flux, so I have to split the work between matrix browser in hypermesh to get volume and then I have to query heat flux in hyperview and then use MATLAB to merge the two datasets. I have two questions. 

 

1. How do I go about selecting the elements in the Matrix Browser of Hypermesh? Is there a way to preselect a specific geometric location that is a little more exact than just clicking and dragging a window? I need this window to be exactly on the intervals mentioned above. I'm looking for the element ID and element volume.

2. Exact same question as #1, however, how do I do this in hyperview for the heat flux? 

Also important to note, that I can't manually do this. I have approximately 50 models that I'll need to do this to, so I'm looking for something that is fairly automated. Don't mind allocating 5 minutes per model, but I can't spend an hour on each model.

You could get the volume from HyperView as well. Using advanced math, and result math, you can retrieve element volume. Then you can query both results, flux and your newly created volume. This topic might give you some insight.

You could save a report template and just reload it for each new result/model.

Hope this helps you.

Sorry for just getting back to you on this subject. Playing with Derived Results, but I only see Math and Expression. I don't see anything related to model (see screenshots). I don't see an option to switch to model. Model was loaded as .fem and results as .h3d

Could you give me just a little more assistance? I'm going to actively try this avenue to get my data.

you probably forgot to load your model using the 'advanced' math template. (this can be found when you select the .fem and .h3d files.
