code_saturne User's Forum

Hi, as many of us have been struggling with installing of CS and Syrthes, I have prepared installation instructions (attached) for Ubuntu 16.04 LTS 64 bit. Instructions cover: - Salome Meca 2016-1 - Code Saturne 4.3 - Syrthes 4.3.0 with a few simple test cases. I hope you find this useful and let me...

Hello, I have a similar problem (running on Ubuntu 15.10). I made a correction to cs_package.py ("self.name = code-saturne " to "self.name = code_saturne"). But now when I run SaturneGUI i get: Traceback (most recent call last): File "/usr/bin/code_saturne", line 76, in...

Hi,

I used the reference file of correct version and added/adjusted the routines from Brians example.
Now it works as expected.

Thank you for help - I am posting the final code (attached).

Brian, thank you for your help. I tried using subroutine that you attached. I got errors when compiling that there are symbol conflicts with module entsor (attached as log 1). Then I renamed some symbols (ifac, ilelt , nlelt, iflmab, keylog) as (ifacb, ileltb, nleltb, iflmax, keylox). The calculatio...

Hi,

I am using CS 3.3.2.
What would be the appropriate (easiest) way to output the mass flow through outlet or inlet.
I need a periodic output - similar to the output of monitoring points - for further evaluation.

Best regards

Hi,

the problem has been solved.
I am just posting corrected cs_user_boundary_conditions.f90 if someone finds it useful.

Hi, - I wont forget to post the error message next time. - I think applying the pressure on both inlet and outlet (both single) should be OK, as I am trying to calculate mass flow at imposed pressure differential (I do not think the model is over-constrained). But until I get the model right I will ...

Hi, I am using CS 3.3.2 and Salome-Meca 2014.2 as pre/post-processor. I want to apply constant pressure to inlet / outlet. I copied cs_user_boundary_conditions.f90 to /SCR and naively modified it to apply a pressure of 4 bar to inlet and 1 bar to outlet. There is probably some very noob-like error i...

Hi,

I think I may have figured out what was wrong with my model.
Apparently boundaries defined as walls, inlet, and outlet have unmovable mesh.
When I assigned symmetry on front and back boundaries, the cylinder could move as expected and mesh deformed appropriately.

Hi Yvan, I have tried calculating with different time steps (0.1, 0.01, 0.001 s). In all three cases the results were virtually identical. Calculation fails at 14.5 s of simulated time in all three cases. What I find very strange is that mesh viscosity, as such, has virtually no influence. I would r...
