Maximum Energy Error
Energy conservation is a measure of the quality of an explicit dynamic simulation. Bad energy conservation usually implies a less than optimal model definition. This parameter allows you to automatically stop the solution if the energy conservation becomes poor. Enter a fraction of the total system energy at the reference cycle at which you want the simulation to stop. For example, the default value of 0.1 will cause the simulation to stop if the energy error exceeds 10% of the energy at the reference cycle.
The global energy is accounted as follows:
Reference Energy = [Internal Energy + Kinetic Energy + Hourglass Energy] at the reference cycle
Current Energy = [Internal Energy + Kinetic Energy + Hourglass Energy] at the current cycle
Work Done = Work done by constraints + Work done by loads + Work done by body forces + Energy removed from system by element erosion + Work done by contact penalty forces
