Im not sure if anyone is able to help me on this. I am currently a masters student doing my thesis on bench-marking open-source or low cost CFD packages. I am currently benchmarking this case below [image] Isolated Building Aerodynamic Analysis by CalvinVW | SimScale CFD validation cas…

Hi Guys just thought I would quickly share my findings roughly. Using the different K values definitely Made a significant impact. The graphs are velocity profiles at different x positions, he first two are from the top of the building to the top of the domain and the last is from the floor to the t…

Hi Calvin! Good to have you here :slight_smile: Sounds like an interesting case! Let me tag my fellow colleagues @cfd_squad who might have a quick look on this issue. I have no machine nearby and would check later on :slight_smile: Best, Jousef

Thank you so much Jousef :smiley: Best, Calvin

Hi Calvin, right now I am running your case, I will let you know once I have results.

Cheers Tolga for jumping in here! Let us know how things go, maybe @DaleKramer , @Retsam , @Get_Barried or @anirudh2821998 can jump in in case of an emergency :wink: Thanks! Jousef

Thank you so so much, you are honestly a life saver!!:smiley: I really can’t thank you enough. Everyone in this community is so incredibly helpful and nice here.

quick update, it takes a bit longer than I thought, so far the residuals [afbeelding] unfortunately it will save the first set of results at 1000, so gotta wait a little longer, what results are you aiming for? You could check if the results at 1000 are accurate enough yet.

Wow are an absolute legend! Ive run a the other packages to 2000 iterations but there was an insignificant difference between the results at 1000 and 2000 iterations and from what I seen K is below 1e-3 which is where I was for the others which is perfect.

Yeah this simulation takes forever! Running locally takes me around 4 days on Code Saturne with 6 cores at 4.2Ghz and 64GB of ram

Great job Tolga! Also thanks for the kind words @CalvinVW ! Would be really interesting to see the outcome and maybe write a nice documentation for this project as it was done for some others like this one right here: Turbulent Flow around City Blocks . Let us know if you have any further wishes and…

Thanks for the kind words Jousef and Calvin. Calvin right now the project is past 1k iterations and you can see the first results. The project link is here SimScale , please let me know if there is something I can help with. Also would be great to see the results of your project.
