Strain energy

Altair Forum User

Hi,

I'm going to perform the convergence study by changing the mesh size and checking the strain energy. In Hypermesh, I couldn't find the strain energy in the list of parameters when I tried to achieve the results of each simulation (Below Fig). Is there any specific engine command to export this parameter? The engine file is in second screenshot. In advance, I appreciate you for taking time to answer my question.

Hi,

When material is deformed by external loading, energy is stored internally throughout its volume and this internal energy is also referred as strain energy.

Create an output block and under VAR type IE, and from the time history file, T01 plot the internal energy for the part required in HyperGraph.
