I do not know if this would be good solution since it is true that interactions are isolated but they are also deleted so it is not the right manner perhaps to store energy variables. I will try to do the same as Bruno did for the friction dissipation and see how the accumulator works. I guess its use, for such cases, becomes necessary then.
