Help with Splashfoam
I've been trying to learn OpenFOAM and SplashFOAM looks like a blessing so far. As I am trying to mesh following the SplashFOAM webinar on YouTube, I get the error saying openfoam2306 is unavailable. I wanted to see if I can change the working case to OpenFOAM 2406 before I install the older one. Any help regarding this would be appreciated. Thank you for your time. P.S: I've tried the contact us page on simulitica website, it just redirects saying address currently unavailable as I try to submit a request, hence my posting the question here.

Hey, thank you for getting back to me! I downloaded this version of SplashFOAM from the git hub guide.

Also, a quick update, I see only openfoam2312 and openfoam2406 in the library/openfoam directory. I tried renaming the 2406 folder to 2306, when I do so, it now says openfoam 2406 is missing.

Run your Simulations on the Cloud Using SplashFOAM
Hi everyone! Happy to give you a quick update! CloudHPC is now fully integrated into SplashFOAM, making it easier than ever to run your OpenFOAM simulations directly from your local machine to the cloud! With this new feature, you can configure your case, submit it to CloudHPC, monitor job status, and receive results—all without leaving the SplashFOAM interface. No more manual uploads or complicated setups. It's all about streamlining your workflow! 👉 Register for a FREE CloudHPC account: https://cloudhpc.cloud/form-request/ 👉 Read the full article: https://cfddose.substack.com/p/how-to-run-your-cfd-simulations-on

Hey, perhaps a bit unrelated, but I am trying to run Splahfoam on Ubuntu. But I am receiving the error _tkinter.TclError: couldn't connect to display "localhost:0". Pardon me if this is not the right place to ask, the guy page directed me here. Please guide me to the right place to ask this question.

Introduce yourself to the group 👇
Hi everybody! Happy to have you all here and very excited to kick-start a long journey of mentorship and growth with all of you. To help get to know each other and break the shyness, take a moment to introduce yourself below and let others know what you're currently working on (CFD or in general). ** Please make sure you have carefully read this post and participated in this poll [takes 5 seconds] Let's go!

Hello everyone. I am Anirudh Diwakar, pursuing my Master's in Aerospace Engineering. Despite taking CFD courses, my knowledge of the field is in pieces. I want to stitch together my knowledge in CFD. Hope to learn a ton here!!

Doubt!!
Hi everyone, I'm working on a problem statement as mentioned in the attachment. The Re=200 for the inlet. I have kinematic viscosity but didn't got any x(length) Should I assume x=1 and calculate inlet velocity. And should I use bulk velocity (i.e. 2/3 of v_max) to calculate Re at upstream an step

@Sai nihal Kunchakurthy the characteristic length is usually where you see an appreciable change in flow regime for your problem. In pipe flow, it's common to take diameter due to the presence of boundary layer, and in ideal cases, the flow doesn't develop over the length, I think. For an airfoil, it's the chord length. It totally depends on the problem.

Turbulent Times
In my opinion, CFD is a very vast and interesting subject and tool but the one thing which seems to be very enigmatic is turbulence modelling. My question here is quite simple: 1) How would you explain turbulence and turbulence modelling to a kid? 2) Why do we have so many turbulence models and why is it so hard to model turbulence accurately? 3) From an aerospace perspective, does anyone have ideas of How turbulence works in Hypersonics? Or do we even have turbulence there? Would love to see some interesting answers on the same!

I feel like my understanding of turbulence is still rudimentary and near to that of a kid. 1. From my understanding, in the most basic layman terms, turbulence is the loss of fluid flow structure due to presence of friction. Similar to how once we slide on a wet floor, we eventually slow down. In this process of slowing down, different people slide in different directions due to the inherent randomness of the process. 2. From my understanding, turbulence modelling is mostly statistical and a probability estimation. Most models that we use try to use many assumptions to basically get values if local randomness that we have no way to measure. Please correct me if I am wrong here. I would very much like to learn of this point in more clarity too. 3. No idea on this. Pardon me if this is not the answer you were looking for. This is just my, perhaps wrong, understanding of turbulence.

I want to learn CFD to apply it to an aircraft of my own design.
