I set the outlet as "isolib" and the inlet like this in “cs_user_boundary_conditions.f90” . But it was divergence. itypfb(ifac)=iindef icodcl(ifac,ipr) = 1 rcodcl(ifac,ipr,1) = 1.e5 icodcl(ifac,iu) = 3 rcodcl(ifac,iu,3) = 0 icodcl(ifac,iv) = 3 rcodcl(ifac,iv,3) = 0 icodcl(ifac,iw) = 3 rcod...

hello,
How to set the pressure inlet boundary conditions in version 4.0?
The case is an incompressible fluid. I want to fix total pressure of the inlet and static pressure of the outlet.
thanks!

Hi,
I'm using v4.2.1 to simulate sandia swirl flame(SM1). The simulation can not reach a converged solution, but it can reach a converged solution without swirl. Would anyone give me some guides on how to simulate swirl flow?

Hi, everyone when I use the model of heavy fuel oil combustion, the results was not right. The temperature was significantly smaller than the expected? The fuel was kerosene. The boundary "Inflow" was pure air, and "fuel" is pure kerosene. The "dp_FUE" and "cs_user...

Hello, In what routine are you changing the value for ipepa(jisor,ip) ? This should work to remove particles. As for particles the log frequency, the associated keyword seems not to be documented, except in the GUI. Is there a reason you cannot use the GUI (combining it with more advanced user subr...

Hi,every one Here I have some question about particle tracking in version4.0.2: Question 1 : what can I do if I want to delete a particle. I make the particle ipepa(jisor,ip)=0 in version 2.0.6,and then this particle will be deleted. But I do it in version4.0.2 by same ways, I found it did not work....

Hello, Somebody else recently asked about parallel runs on this forum, so you should find more info here. About nvisla, Particle writers in version 4 behave similarly to the standard "Eulerian" writer, so you can adjust the frequency in the "calculation control/outputcontrol" se...

Thank you for your replay.I use code_saturne 4.0.2 with no GUI.So can you tell me how to control output partical massage

Hi,everyone:
can you tell me how to use code_saturne with Parallel computing.By the way,I don't know how to control the frequency of twophase result output which by nvisla in version 3.0.
Thank you very much.
