Summary:

This video, a continuation of [tubulFEsim1EN], presents simulations with a different number of elements and with a different value of the interpolation coefficient β, different from the theoretically necessary one to accurately replicate the energy balance in a steady state (equilibrium). The changes of β allow to reduce the artifacts in the step response simulation... although if the inputs do not change suddenly, they may not be a problem: the discussion is parallel to the video [approxretEN] where the approximation is discussed of transport delay specifically.

This ends the case study on the tubular heater that began in the video [term1eEN]; a summary and final conclusions about the case study in general will be addressed in the video [tubulconcEN].
