TKE Budgets LES

Good morning,

I would like to know the partitioning between the resolved and modeled velocities from a LES simulation. Is there a way to tag each of these variables or to calculate them based on the output variables ?

Thank you for your help,

Marcia

RANS/LES restart

Hello, I have a question regarding the restart process in the case of a LES simulation. My objective is to initialize my LES simulation from the results of a RANS simulation. To do this I use the restart option and read the checkpoint folder from the RANS simulation (which has the same configuration...

Re: Periodicity and scalars LES

Hello Yvan, My colleague ran a debugger and the problem was a post processing variable that was included in the list of variables for the creation of profiles. When using the GUI this issue was not signaled and you could only see it when opening the setup.xml file with a text editor. The coupled sim...

Re: Periodicity and scalars LES

Hello, My colleague installed the debug version and he hashed the call for icorio. I tested a single domain (no coupling) case and it worked fine as well as a single domain case in parallel mode. However, I tried to launch a COUPLING case and I still encountered an error, specifically the "erro...

Re: Periodicity and scalars LES

Hello, My colleague verified the installation and reinstalled it using intel MPI. Although the installation seemed to pass we now get an error related to the writing of results when launching a simulation. I have attached the error from a test we performed as well as the config.log files from the co...

Re: Periodicity and scalars LES

Thanks for the prompt reply,

I do not know about the use of MPI during the installation, however, I launched a test with no coupling and it run as expected. I am not sure if this is the test you suggested. I have attached the log files as well as the runcase file for your perusal.

Re: Periodicity and scalars LES

Dear Yvan, I tested the coupling option you proposed and it answered to what I was searching to execute, however, I have encountered issues when launching a Coupled simulation using the new stable version 6.0. This version was recently compiled in the computational server we use. The error I get in ...

Periodicity and scalars LES

Hello, I am currently working with urban atmospheric dispersion simulations. I have a regular geometry which allows me to use periodic conditions for the flow and I have successfully run simulations with RANS and LES (using my RANS simulation as restart ) using CS v6.0. I would like to add scalars i...

Vorticity field and Q-criterion LES simulation

Hello, I am working on LES simulations of the urban boundary layer and I would like to analyze the turbulence structures using the vorticity field and the Q-criterion (Hunt et al. 1988). I know I can do this with Paraview but I would like to avoid doing this step in the post processing. How can I ad...
