Hi there.I completed a plants static simulation and the dynamic simulation works untill the last column .there are 5 column over all and all other streams and columns before the last one just works fine. when i start the simulation the last stream coming out of reboiler suddenly starts to drop pressure and then pressure solver stops.the stream going to column and the stream coming out of condenser are fine while i check the fixed pressure profile. what could cause such problem? i'd really appreciate any help
