Hello,

I was analysing the history output for different energies and observed that major contributor to 'ETOTAL' i.e. total energy which has a constant value of 4675 J was the internal heat energy 'ALLIHE'. The value of ALLIHE was highest among all energy variables and is also remaining constant at around 4674 J.

Can anyone explain or point to a source where I can find the reason for the value of ALLIHE being so large? What is ALLIHE constituted of and how does ABAQUS calculates it?

I tried looking into ABAQUS documentation, but there was no mention of how it calculates ALLIHE or any sort of definition for it.

Any suggestion or helpful tip is welcome!

Thanks,
Ankit
 
Heat Energy = Degrees above reference temperature x Mass x Specific heat capacity

For 1kg of water 1 degree above reference temperature is equivalent to 4185.5 Joule.

E_h = T_r x m x c_p

Good luck
