Hello, I am using Ver6 and running simulations in Ubunts18. Here you can get some files for computation (run solver log and compile ...) https://filesender.renater.fr/?s=download&token=bfebdc6b-d770-4f13-b784-1c1e150ac278 Now I run simulations for scalar transport. The procedure of my simulation...

Hello, I have a question about the mapped inlet. I have never used the mapped inlet, I know some people used it to make a pseudo-periodic boundary condition. You can see a picture I want to calculate. (Geometry is simplified very much now to show you clearly.) a.png As you can see, there is a space ...

Hello,
I just want to know What are "Friction velocity uet" and "Friction velocity uk"?

In the uesr guide, I found "uk" related to kinematic energy, but I could not find "uet".

Would someone tell me this?

Best regards,
Tsubasa

Hello, Sorry the title of the topic is not clear. I am doing simulations for outdoor and indoor separately. Then what I want to do now is 1. outdoor flow simulation and extract a velocity profile (surface profile (2D), not 1D profile,) at a certain plane near a window which I select 2. impose that s...

Hello, I wonder simulation results are different if machines are different. I run two simulations with the completely same setting. Surprisingly the results are not identical at all. I run 12000step, and in the first 50steps the results are the same as each other. Is it true? I think a very very sma...

Hello, Now I am writing a paper and I am lookng for the detailed numerical discription of k-w SST and pseud-steady simulation. As fas as I know in the past post, there is no discription about k-w SST in theory guide, right? But maybe it is similar to k-epsilon model, so I can check it in other paper...

Hello Yvan, I compared two pollutant simulations; one with Sch(schmidt number)=0.7 and the other with default Sch. So far I thought default Sch in codesaturne is 0.7 according to src/cogz/coini.f90 following CODE: SELECT ALL ! ---- Schmidt ou Prandtl turbulent turb_schmidt = 0.7d0 call field_set_key...

Hello Yvan, Actually I think I found a option in GUI which is similar to what I want to do. You can find a picture attached following: SourseTerm.png By this, can I set volumic injection? If so, could you let me know hot to set a size of volume for source? (In tehe examples tab in GUI, there is noth...

Hello Yvan,

By using the volume mass injection, is it possible to set a point source and line sourse for pollutant injection inside domain?

Best regards,

Hello, I am wondering it is possible to set species transport inside a domain? You can understant what I mean in these pictures. First picture is computational domain. Second one is a boudanry to set a species transport which is located boundary of the domain. Third one is a boudanry to set a specie...
