Re: Periodicity in Buyoncy driven flows

Hi Yvan thanks for relying. My case is laminar. yes i want to estimate exchange coefficient h. Wall heat flux qwall is unknown. Delta T (temperature difference) between horizontal walls is known. I looked deeply into that nusselt subroutine you mentioned. It does not work for an unknown qwall: atlea...

Re: Periodicity in Buyoncy driven flows

Hi Yvan, thanks. I have been working on the buoyancy driven flows in rectangular cavities for sometime now. i am facing a difficulty that does not seem to resolve. It is related to interpreting code-saturne results. I would be really thankful if you could share anything that could help because i am ...

Re: Periodicity in Buyoncy driven flows

thanks yvan, selection criteria is clear to me but i am still clueless about the translation vector. Is there any document/tutorial/manual you can refer me to to understand what for example 1 in (1,0,0) physically mean or refer to and how it came about?. Thanks

Re: Periodicity in Buyoncy driven flows

Hi Yvan: No, there is no backtrace error file if I interrupt. If you remember, I upgraded CS to CS 4 but it messed up CAE Linux installation so bad that I basically had to re-install. Same happens if I upgrade ubuntu. Basically, its an issue at my end due to lack of linux know-how and lack of on-sit...

Periodicity in Buyoncy driven flows

Hi there: I need help with periodic boundaries setup. I am having difficulty understanding translation vector and selection criteria. My Case: I have a pure natural convection case between two parallel plates. Flow is driven through boussinesq approximation hence no pressure gradient is required. I ...

Thermal Boundary Conditions Code Saturne 3.1: help needed

Hi Yvan: I wish I could have found a more independent help on thermal boundary conditions in code saturne 3.1 but i could not hence writing to you. I am flexing my hands on free convection problems in complex geometries for which nusselt number correlations do not exist. I am starting with very simp...

Re: Mesh partition and computing geometric quantities

Hi Yvan I wiped clean my system and installed latest CAELinux2013 which has code saturne v3.1. I still cannot update to code saturne v4 without immense issues. Anyway, its a clean install. I am running old case with a user subroutine called extra operations to calculate lift and drag coefficients. I...

Re: Mesh partition and computing geometric quantities

Hi Yvan Sorry to question time and time again. I ran LES simulation on cs4 in order to see if it gets stuck in the same fashion as it did in version 3. But the solver didn't run and gave the following error. /opt/Saturne-4.0.5/code_saturne-4.0.5/arch/Linux_x86_64/libexec/code_saturne/cs_solver: erro...

Re: Mesh partition and computing geometric quantities

Hi Yvan: I followed your advice and I figured out that removing the line : source /opt/caelinux/.bashrc-CAE makes the terminal stable but then i loose all short commands and aliases of all the CAE tools which are defined in .bashrc-CAE. Which means the terminal is not sourcing the bashrc-CAE but it ...
