hello
I am new user to FLEXPDE. I want to simulate mass transfer from gas phase (upper part) into liquid phase (Lower part). I have 2 quesion) . It is my appreciate if you answer to both of them.
1-I don't know why my concentration is taking negative at the starting point.upper phase is my source and lower phase is my sink.
2- during diffusion some moles are transfering from gas phase to liquid phase then pressure of system is reducing exponential but I don't know how can I define my FLEXPDE code. some times pressure is going to increase and some time decrease.how can I apply the upper part shoud be my source the same conduction (without moving).
regards
Bahar
