Cosmos Works 2007 - In an effort to approximate an impact loading limit I need a total strain energy value of the entire structure in my simulation. Contrary to what you might expect, selecting Total Strain Energy in the Strain results provides only individual element values. Is there a way to extract the strain energy value for the entire structure? Thanks in advance.

Dave,

If you look in your study results folder, there is a .OUT file. Open this with notepad, wordpad, whatever. You'll see at the end (at least for a static study) an entry like this:

Total Strain Energy (TSE) = 0.248978E-06

Total Error Energy (TEE) = 0.188175E-08

Ave. Percentage Error (APE) = 0.613573E+01

( APE = sqrt (TEE/(TSE*2. + TEE)) * 100. )I believe that is the total for the entire system.

BrianThe total strain energy is the area under the load deflection curve. What I frequently do is use the probe tool and plot the force vs deflection, export to excel and integrate to get the input strain energy. This should ovbiously be pretty close to anything output by the program given energy in equals energy absorbed.
