Hi,

I am running a a very simple transient simulation: turbulent flow through a rectangular channel; all walls are insulated; constant T,U inlet; buoyantPimpleFoam with sensibleEnthalpy

I cannot satisfy the intregral energy equation in manual post processing. I've attached geometry and integral equation. Since all walls are insulated, AT EACH TIME STEP:

Net energy coming into the domain = rate of change of Energy in control volume

But net energy coming into domain is higher than rate of change of internal energy.

I would appreciate any help. Thank you.
