Hello everone, I’m running an FSI case which is a jet in the fluid domain impinging on a hyperelastic body in the solid domain. I use the hyperelastic material in calculix and analyzed it with dynamics module. Since calculix cannot output pseudo strain energy（ALLAE）, like abaqus, I would like to know what the energy balance in the output of the screen means and how I can evaluate its magnitude.  
Please help me, thank you very much 😊

Relative energy balance equation can be found in CalculiX User’s Manual - page 356, chapter 6.10.5 Implicit dynamics: [http://www.dhondt.de/ccx\_2.20.pdf](http://www.dhondt.de/ccx_2.20.pdf)
