I managed to get the results by refining a lot on the sides of the duct.


Well yes, it is like a very huge pressure wave. And I wanted to study what happens when putting a so big pressure at...

Well, I have to check that I get U=2.68m/s at the end of the transient time, for a 30bars deltap! So I will not change my initial conditions.



I just have to check that my simulations suits to...

You're right, I corrected it and got Re = 53.6.


I use Darcy formula to get the average velocit: U = deltap*Dē / (32* nu * rho * L)

In this case, I get U = 2.68 m/s.


Then, Re = U*D / nu.

Thanks ! Yes of course I understand now... I did it and the calculation runs longer but still it crashes...


My last cylinder test:
D = 0.001m
L = 0.07m
nu = 0.00005 mē/s
deltaP = 3 bars...

Is not it what I am doing by setting the "endTime" to 10e+6 and "deltaT" to 1 in controlDict? It is the same than putting respectively 1 and...

Smile icoFoam simulation - Poiseuille cylinder

Hello,


I managed to use simpleFoam for my simulations in steady-state! The problem now is for the transient part of my study. As I am a very beginner I tried to use both pimpleFoam, pisoFoam...

Yes you're right. I made it work today, I juste changed the turbulenceProperties file to a laminar simulationType ans it has been ok.
I would like to make the transient form work too (icoFoam) !...

Smile Simulating a steady-state/laminar/incompressible/newtonian flow

Hello everyone,



I am totally new on OpenFoam. I practiced on tutorials and thanks to some videos/forums. Nevertheless I am facing a problem:

Which solver do I have to use to simulate a...
