Hello for everybody!
I am a student of Master of Science in Petroleum Engineering, Torino, Italy. I am doing my thesis with COMSOL. The theme of my thesis is an "Application of a FEM simulator in mulltiphase flow in porous media". As a basis I am following the paper of Diaz-Viera: "COMSOL Implementation of a Multiphase Flow in Porous media"
I am trying to simulate with COMSOL a simple multiphase flow model using 1D -PDE, coefficient term-time-dependent analysis.
Let's say that I am injecting water from 1-st boundary and I would like to close the second boundary making "No flux boundary conditions". At the end I should obtain a plot with increasing pressure.
But I cannot set "no flux boundary conditions". Please, help me.
I will attach file with the model where I want to set "No flux boundary condition" for the second boundary.
Thank's in advance.
Best regards,
Marziya Aliyeva

Hi
There is multiphase module in COMSOL (in Chem Eng) where you can use ready made equations. Also, your problem looks like very similar to an example in Earth Science Module, two-phase, oil-water flow.

Hi, thank's a lot for your reply.
But I must use PDE models, I shoudl put equations, expressions by myself. After doing it I should compare my model with the other softwares lwhich are based on Finite Difference method. So, that's why I am using PDE models.
