Negative Total Energy????
Negative Total Energy????
(OP)
Is it possible for total energy to be negative in abaqus simulation? For better understanding of my problem I attached the screen shot of the process.

The three big components are: External work (ALLWK), Internal Energy (ALLIE) and Plastic dissipation (ALLPD). It seems that the big value of eternal work is driving the total energy to be negative. Is it ok to be negative? I mean can eternal energy get bigger than internal energy?
