code_saturne User's Forum

Hi, I am using CS 3.0 to simulate the electric arc, and have a question about the plasma beta in this module. Plasma Beta is the ratio of gas pressure to the magnetic pressure. Is there anyone please tell me what is the plasma beta applied into the Code_Saturne? Is less than 1, near 1 or lager than ...

Dear Yvan, Thanks for your quick reply. I will check the user manual of CS4.0. Unfortunately, I didn't get any help for doing the solid/fluid coupling, I studied some papers or thesis that consider the electrodes into the computational domain and these papers show some results, so I want to simulate...

Dear all, I would like use CS 3.0.0 to consider the electrodes into the computational domain. So, I need to model the solid/fluid coupling in CS 3.0.0. Could anyone please help me to solve the following problems? Thanks. 1. How to add the source term in momentum equation? I would like to add the sou...

Dear all, I have installed CS-4.0 Windows x64 version on my computer, however, after finishing all the settings and try to run the simulation, I got the blank screen and the CS is not running (please refer to the attachment file to see my screen). Can anyone please tell me how to solve my problem? T...

Dear all, I would like to simulate the electrical arc between two electrodes by using Code Saturne 3.0.0. I got the results without considering the electrodes (solid) into the computational domain. Now, I would like to consider the electrodes (solid, cooper or graphite) into my simulation. I already...

Dear all,

Could anyone please tell me what is the meaning of the following variables in uselrc.f90?
(I am using CS 3.0.0)

Line 348: dtj
Line 349 dtjm
Line 350 delhsh
Line 351 cdtj
Line 371 cpmx

The attach file is the subroutine uselrc.f90, thanks for your help.

Best Regards
Eric

Dear Brian Angel,

Thanks for your reply!!!

Dear all, I would like to simulate a DC electrical arc between two electrodes, however, when I try to control the arc current by using uselrc.f90 subroutines, I always have the divergence error. In other words, if I don't use the uselrc.f90 in my model, I can run the simulation. Also, if I use the u...

Hello, Actually, I am curious about what are the change for "elec" subroutines from CS2.0 to CS3.0 Recently, I try to simulate the DC electrical arc between two electrodes, and I found some references about that, however, that simulation is based on CS2.0, so I try to figure what is the di...

Dear Brian Angel,

Thank you again!!!
