Dear I have a follow-up question. nIn the picture below, a diffuser is added on the other side of the chamber. This diffuser is parametrized similar to the nozzle per your suggestion. However, how can I ensure that the position of the diffuser stays within the limit of the chamber height, i.e. such that V5+L2+V6 >= V10+L16?nRight now in my DOE I used the limits [0,05 0,2] for V5, V6 and V10, and [0.2 1.0] for L2.n
