Unable to acquire in post-processing for crash simulation of inflated body

Sir,

I want to perform a crash analysis on an inflated structure. The problem I am facing is about the type of MONVOL to choose. Since its not exactly an airbag, I doubt whether GAS Monvol is to be used. I have performed a simulation with the inflated structure(MONVOL-GAS-Pint-0.2MPa) whose purpose to absorb the energy of impact and prevent the damage to a bullet and a target vehicle. However the postprocessor is showing no deviation in K.E, I.E and Hour glass energy. Even the contour show no particular deformation. How can I quantify the energy absorbed for the same in that case?. I only want the energy absorbed data of 3 bodies, kindly suggest me a solution. I am attaching an image of the hyperview( used monvol-airbag). Is it necessary I give airbag effect or can I move forward with Gas monvol?
