How do I obtain Total Heat Flow (not heat flux)

I need to calculate thermal conductivity. I have a model that outputs heat flux across each individual element; however, I need to be able to extract the heat flow from those elements. So, I have a few questions.

1. Is there a way to obtain heat flow from heat flux?
2. If there is not a way, how can I obtain the surface areas of each element on a plane?
3. Is there a way to just get total heat flow on a plane?

Please don't use jargon. I'm still pretty new to this system and it's hard to navigate if I'm given a highly technical answer. 

Background: Using Hypermesh 2019 (Optistruct) for this. Elements are not all the same size.

    you coud do it through scripts or using the Matrix Browser to export your relevant data.

     

    This topic shows you an example of Matrix Browser with a video (ahtough it is japanese).

    With Matrix Browser, you could easily load your FE model, and also your result file, and then extract your relevant data and export this to Excel.

     

    You will launch Matrix Browser from HM, and query your interest elements.

    From these elements, you can query their area. Matrix will populate your table with the area of each element selected.

    Then, having a second window, with HyperView, you can query 'model results'. In this case you can get the Heat flux for each of your original elements.

    Then export this and do some math.

     

    I hope this helps you.
