WebJul 4, 2024 · In the geometrical linear analysis, the internal energy (ALLIE) and the work done (ALLWK) are equal. So, with ETOTAL = ALLIE - ALLWK, the total energy was zero. But in the case of geometrical non-linear analysis, ALLIE > ALLWK and the total energy (Etotal) was increasing over the time. WebThe first law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes.A simple formulation is: "The total energy in a system remains constant, although it may be converted from one form to another." Another common phrasing is that "energy can neither be created nor destroyed" (in a "closed … iris by the goo goo dolls
