Re: A question on restarting file

Hi Yvan, I am sorry that I did not include the subroutine in the previous post. It is attache now. Best regards, Yu. Hello, Most quantities are computed, but turbulent values are not (it is easier to restart from k-epsilon to k-omega, as turbulence variables are "converted"). You may try to initiali...

Re: A question on restarting file

Hi Yvan, Thanks for your suggestions. But I did not find the 'usiniv' on the cs_user_initialization.f90. I am not sure whether it is because the version of code_saturne is different from yours. I am using code_saturne 4.0.2. Can you please give me hints? Best regards, Yu. Hello, Most quantities are ...

A question on restarting file

Hello users, I need to use k-omega-sst to do some simulation. However, the simulating case keeps diverging. To make the simulation converge, I tried to simulate it is as liaminar flow. This gives me a very rough predictions, I turned on the turbelence model afterward. However, as there is no fiel fo...

The Error when running the simulation

Hello Users, When I wan trying to run the simulation withe very thin viscous layer. K-omega-sst model was chosen and the inner cirulation was set at the inlet. I came across the following error: /home/martian/APP.SRC/code_saturne-4.0.2/src/alge/cs_multigrid.c:2780: Fatal error. algebraic multigrid [...

Re: How to setup the parallel computing of code_saturne4.0.2

Hi Yvan, Thanks for the reply. I had checked the forum before. All of the cases are on using GUI to set up the case. Unfortunately, I did not successfully installed the GUI. Can you please tell me how to specify the number of core I want to use by using subroutines? Best regards, Yu. Hello, There wa...

How to setup the parallel computing of code_saturne4.0.2

Hello users, I am using the subroutines to setup the case in code_saturne 4.0.2. Can you please give me some suggestions on setting up the parallel computation case using subroutines. I found there are some of the subroutines like 'define_case_parameters(case)' are disappeared in the 'cs_user_script...

Re: Installation Error - either use HDF5HOME env. var. or --

Hi Yvan, Thanks for the suggestion. The original problem had been solved. But the new problem came out: configure: error: Could not link test program to Python. Maybe the main Python library has been installed in some non-standard library path. If so, pass it to configure, via the LDFLAGS environmen...

Re: Error on running the simulation via Code_Saturne 4.0.2

Hi Yvan, I thinke there is something wrong with my salome 7.6.0. I used it to generate the mesh and export as .cgns. However, the name I gave to the boundaries are missing. The 'Group 28' is given the software. However, it is not the case when I used the salome-meca 2014.1 to generate the mesh. Rega...

Re: Error on running the simulation via Code_Saturne 4.0.2

Hi Yvan, Thanks for all of your help. The initialization problem solved. But the simulation stopped at the first step with the following error: /home/martian/APP-INST/code_saturne-4.0.2/src/fvm/fvm_selector_postfix.c:1281: Fatal error. Error parsing expression: Group 28 ^ Expected operator instead o...

Unfortunately, it does not work. I just installed one hdf5-1.8.14. I had tried 1.8.15 as well, the outcome is still negative. I...
