Product of volume of a mesh element and its average temperature 2

[Gyawali]

In a thermal transient analysis in Abaqus, I want to calculate the product of the element volume and its corresponding temperature of the whole model in every time step. I have tried using Plugins=>Tools=>Volume Weighted Average Temperature. But I didn't get the result as expected. Is this way correct or is there another way to calculate?
Thank you in advance.

This plug-in is the right way if you want to calculate the average temperature related to the volume of the finite element. What’s wrong with the results that you get ? Why do you think that they are incorrect ?

Thank you for your reply.
Let's say I have 5 elements (E1,E2,E3,E4,E5) in a model and their respective volumes and element temperatures are V1,V2,V3,V4,V5 and T1,T2,T3,T4,T5. This plugin calculates the volume-weighted average temperature as (V1*T1+V2*T2+V3*T3+V4*T4+V5*T5)/(V1+V2+V3+V4+V5). Right?

Yes, they don’t provide the formula in the documentation but that’s exactly how a volume weighted average should work.

For integration points you can request IVOL and TEMP and then use "Create Field Output from Fields" or a script to calculate the product of them.

For the whole element you could use EVOL to get the volume, but there is no variable for the temperature. You might get something close with a field report of the temperature at the element centroid. Afterwards you have to use a script to calculate the product and write it to the .odb.
