[QUOTE="casualguitar, post: 6889047, member: 695787"] Hi Chet, Unfortunately the molar flow error didnt fix the output, although it did change it somewhat. The molar flow out of a tank should have been defined as the below. It was previously this so I must have changed it somewhere along the way: \begin{equation} \dot{m}_j = \dot{m}_{j-1} + \frac{\rho_m \Delta z A_c}{T_g}\frac{dT}{dt} - (M_{CO_2}''*A_s) \end{equation} Further up in the code ##m_j## is defined as: \begin{equation} m_j = \frac{P}{RT_g}\epsilon A_C\Delta z \end{equation} So I now have: \begin{equation} \dot{m}_j = \dot{m}_{j-1} + \frac{\rho_m \Delta z A_c}{T_g}\frac{dT}{dt} - (M_{CO_2}''*A_s) \end{equation} which I've implemented as: \begin{equation} \dot{m}_j = \dot{m}_{j-1} + \frac{m_j \epsilon}{T_g}\frac{dT}{dt} - (M_{CO_2}''*A_s) \end{equation} Just posting this here in case I've done anything crazy there [/QUOTE]
