                    Caption: Figure 17.
Top: evolution of internal energy ﹩{E}_{\mathrm{int}}﹩, gravitational energy ﹩{E}_{\mathrm{grav}}﹩, kinetic energy ﹩{E}_{\mathrm{kin}}﹩, and their sum ﹩{E}_{\mathrm{tot}}﹩ for the envelope shock test simulated with MESA and V1D. Bottom: log of cumulative relative error CRE (Equation (58)) of the total energy ﹩{E}_{\mathrm{tot}}﹩. We neglect sources (nuclear burning) and sinks (radiation losses), which are negligible.
