Hi everybody !
I am solving a simple case of fluid mechanics using modules "Laminar Flow" and "Transport of diluted species". The case is simple : I inject a fluid (water) in a network (concentration = 1) from a specific boundary from t=0 to t=1, and I would like to inject (again) a fluid (water) from another boundary from t=1 to t=2. I want to do my second injection considering the network already filled by the first injection. To do that, I need to start my second Time Dependent study-step using last solution of the first Time Dependent study-step as initial condition. I succeded running both simulations independently, but for the second one, I can only see my fluid spreading in an empty network (without the c=1 from the first study). I think that I have a problem with my settings or that I forgot something. Maybe in the section "Initial values of variables solved for" or "Values of variables not solved for".
If someone can help me, I would be grateful.
Thank you in advance,
Florian
