    Hi,

    Wat if energy error still remains high even with out any friction?

    In my case the energy error is linearly increasing till 55 % and comes down to 3 % at the end ( with Zero friction). Is this ok ?

    Hi Kathic,

    In certain situations high energy error can be acceptable:

    > If the initial energy in the system is low, then it is possible to have large Energy Errors early in a simulation that reduce as energy is added to the system. 

    >Large contact energies relative to total energy can cause large negative Energy Errors because contact energy is not part of the Energy Error equation. If the simulation has friction and a lot of sliding contact, then the large contact energy and resulting energy error can be considered acceptable.

    So i feel in this case the energy error is acceptable.
