Thanks Yvan, I will do that and keep update the post later

Hello, Yvan, I move my previous post here as sugested by you. I attached the setup programmes. My mesh is msh and it can't be uploaded to the forum apparently. It is a structured uniform 1000 hexa elements mesh along 10 mm in x. In the BC programme uploaded, concetration is set at 1e3. If you change...

Hello, I was making some test because I want to perform some calculations of mixing in small channels and I found the following result: Imagine a unidimensional diffusion problem say a structured mesh on x direction of 10 mm, with 1000 elements. On one end I set a dirichlet condition for my salar, a...

Thank you Yvan for your answer. I am already imposing pressure (0 Pa) at the outlet also. What I want to know is if one can impose a pressure difference and let the flow adapt to that condition in Code_Saturne. I agree with you it is more common to impose velocity at the inlet, but I want to compare...

Ok sorry, I translate my question: I would like to impose a dirichlet bc for the pressure: I'm running a 2d case of a jet, with an inlet where I can either impose a velocity or a pressure, and then this channel flow will exit into a chamber (a box with exit bc where I use isolib bc). if I fix the ve...

Bonjour, j'ai un souci lorsque je veux imposer une pression comme condition de bord: mon problème c'est un jet 2D, avec une entrée ou je peux fixer soit la vitesse, soit la pression, puis plusieurs sorties ou j'utilise isolib bc. Si je fixe la vitesse à l'entrée: call getfbr('3',nlelt,lstelt) ! ====...

Thanks Yvan, I'll keep on working and check on the forum from time to time so see if there is an update on the other questions.

Hello Yvan, I have read the theory documentation of the versions (1.3.1) and (3.3), condli and clptur. I see no difference between these two documentations. I have compared condli.f and condli.f90 and I see that in the new version there are pointers to gradient boundary conditions 'iclu = iclrtp(iu,...

Bonjour, je travaille sur le module conduction ionique avec l'équipe de Thierry Paillat à Poitiers. Je voudrais utiliser itrmas.f90 pour ajouter un fux de migration d'une espèce chargée au flux de masse rho*u (c'est à dire, pour impliciter le terme de migration) Sur la version 2.0.2, pour le calcul ...
