Re: issues in saturne/saturne coupling with v8.0

Hi Yvan, Many thanks for your reply and prompt action on this. The version that I tested without a problem is v7.0.4, and I did not test other v7.0 versions beyond this. So, I guess, you are right, the issue may be related to the bug fix between v7.0.4 and v7.0.5. With your fix to the bug in the git...

issues in saturne/saturne coupling with v8.0

Hi developing team, I recently encountered issues with saturne/saturne coupling in version 8. I noticed there are some changes to the related source codes compared with version 7, such as in csccel.f90, csc2ts.f90, etc. The changes look fine to me, and I am not sure if the issues are caused by these...

Compressible module in Code_Saturne for supersonic flows

Hello, We are going to carry out some RANS (probably LES as well) simulations to capture the long transients of supersonic jet flows (Mach number ~ 5.0). As far as I know, the compressible module in Code_Saturne is still likely to be a pressure based segregated solver. Is there anyone who has compar...

Issues about adding boundary layer mesh

Hello,

I tested the new feature of adding a boundary layer mesh by subroutine CS_user_mesh-modify.c in v5.3. However, the geometry of the domain was modified as well. Does anyone have any idea about this? Thanks

empty monitoring files

Hello, Recently, I found a tricky issue when using Code_Saturne v5.0.8 that the monitoring files are not updated at all since they are generated at the beginning of the simulation. This seems not to happen on some of the machines even with exactly the same setups. Does anyone encounter with the same...

gradient calculation

Hello, I have a self-defined field called 'prev_temperature'. When I calculate its gradient with field_gradient_scalar, it just crushes. The following is the error message. /home/bliu/Desktop/Code_Saturne/code_saturne-5.0.8/src/base/cs_field.c:3351: Fatal error. Field "prev_temperature" wi...

Re: Information exchange for volume coupling

Hello, I've tried both boundary coupling and volume coupling with a simple case (both are external coupling between different code_saturne instances) a couple of weeks ago and will try later. In my boundary coupling test case, two separate domains are connected via an interface. I assume the result ...

Information exchange for volume coupling

Hello, I just started to work on coupled simulation of two fluid domains. In my previous post, Yvan has already mentioned that there are basically two ways to do a coupled simulation (external coupling): one is the boundary coupling (face coupling) and the other is the cell coupling (volume coupling...

Re: Coupled simulation of two Code_Saturne instances

Hi Yvan, I went trough the source code and tried to understand how the coupling works within Code_Saturne, but it seems not that straightforward to understand. Through the documentation, I know that the coupling relies on the PLE library. Is this library used only for the external coupling (coupling...
