First Column: ENZO

Second Column: CHOLLA using physical internal energy when \(ge_{tot}/E > 0.02\) and \(E_{kin} > 0.4 \overline{E_{kin}}\)

Third Column: CHOLLA using physical internal energy when \(ge_{tot}/E > 0.02\)

Forth Column: CHOLLA using physical internal energy when \(ge_{tot}/E > 0.02\) and internal energy synchronization after half-time update.
