Source term for periodic simulation

Hello everyone, I am having some troubles in running a simulation on a periodic domain. To drive the flow and to keep the flow rate at a constant value, I tried to adapt a subroutine written by Yvan Fournier I found in an old post ( http://code-saturne.org/forum/viewtopic.php?f=2&t=1327 ). I hav...

Re: 0-equation turbulence model

Hello, Thank you very much for your answers. I have implemented the model in the way you suggested. It compiles, at least, but I am having convergence problems that I did not have before I introduced it. I am now trying to find out what is actually happening. Thank you again nonetheless Regards, Cos...

0-equation turbulence model

Hello everyone, I need to implement a simple 0-equation turbulence model, where the turbulent viscosity is taken to be proportional to the streamwise component of the velocity. In my plans, I wanted to do so by modifying the molecular viscosity in usphyv and running the calculation as if it were lam...

Re: Order of compilation (plus an unrelated question on find

Hello Yvan,

Thanks for your quick answer.
Putting my module into cs_user_modules solved my problem. I am now going to give a close look to the functions you pointed me to, I hope that won't be too difficult for me.
Thanks again and regards,

Cosimo

Order of compilation (plus an unrelated question on findpt)

Hello everyone, I have a question about whether it is possible to specify the order of compilation of the files in SRC. I have a couple of subroutines and variables that I wish to access from some of my user subroutines, so it seemed a good idea to me to include them in a Fortran module. However, in...

Selection of values on internal faces in version 4.0

Hello everyone, While studying the way to implement periodic boundary condition I stepped into this post , where I found a very instructive subroutine by Yvan Fournier. However, this script relied on the use of the arrays propce and propfa , which as far as I understand are now deprecated in 4.0. Is...

Re: Unable to run a coupled simulation with Syrthes

Hello, Unfortunately, the crash occurs at the very first iteration: I am uploading the complete log, as well as the listing from Code_Saturne. I can't see any problem in the latter, except for the line: Application "solid" (SYRTHES 4) requested calculation stop. Meanwhile, I also noticed t...

Re: Unable to run a coupled simulation with Syrthes

Hello, Thank you a lot for your time. As you suggested, the error was due to the fact that Saturne and Syrthes were using two different mpicc compiler. I reinstalled both and the simulation eventually started. However, my sorrows are not over yet... At the first iteration the analysis crashed, givin...

Re: Unable to run a coupled simulation with Syrthes

Hello,

Thanks for your reply. No, I cannot say I am sure. How can I check if this is the problem and, in case it is, how can I fix it? It's a novice question, I know, but this is what I am...
Many thanks again and best regards,

Unable to run a coupled simulation with Syrthes

Hello everyone, I am experiencing a problem in running my first coupled analysis using Code_Saturne and Syrthes. I am trying to simulate the heat exchange between an internally heated rod and the surrounding flow. Both the fluid and the solid models seem to work properly when tested alone, but when ...
