Hello, I'm using version6 to run a LES simulation. There is an inlet in the simulation domain, and I have an extra inlet pipe where I can apply the mapped inlet function to create fully developed turbulent flow for the real inlet. I noticed that the mapped inlet can be defined through both GUI and s...

Hello,

The run_solver.log, performance.log and setup.log are uploaded.

I'll try to run a RANS simulation then get back to you.

Best regards,

Hello Yvan, I actually had internal coupling in the simulation. The cs_user_parameter.c, cs_user_initilization.f files were not successfully attached to my first post, sorry about that. They are now attached here. The spurious thing I found is that, in the listing file the temperature field seems to...

Hello, I'm trying to run a LES simulation with conjugate heat transfer. The version I'm using is code_saturne-6.0.0. The simulation is restarted from a previous run in which the solid domain was not included. My problem is that I find in the case with conjugate heat transfer considered, the temperat...

Hello, I've managed to solve it. The mistake I made was that when I submit the job, I didn't specify that simulation should run from the cs_solver generated after compilation of the subroutines. Instead, simulation was run using the cs_solver in the folder where code_saturne was installed. Best rega...

Hi Yvan,

I'm attaching the files in the zip folder. It includes the xml file (cylinder.xml), compile.log, performance.log, setup.log, listing file and the user subroutines. The version I've installed is code_saturne 5.2.1.
Could you have a look to see if anything is wrong?

Hi, I found my subroutines are not overwriting the xml file when I run simulations on HPC. I have initialised the case and there is no error in compile.log. But I found the properties I defined by subroutines, such as thermophysical properties were not overwriting those default values set by GUI. Th...

Hi Yvan, I'm using the user subroutines for my simulation. The different scalars I've mentioned are not for the fluid mixture, but for additional fields I need to solve. The fluid density in my simulation is defined variable as a function of the temperature and the pressure, however I want the densi...

Hi, In Code Saturne, can I define a density for the user scalar equation, instead of using the density employed by the continuity, momentum and energy equations? In my simulation, I have set up several user scalars, and I want to use constant densities for different scalar equations, however the flu...
