I wonder if these long runs are common ?

Might need to invest in my own eypc sever (i belive they use a ddr3 system)

My reddit recent tabs really show where my interest lies https://cdn.discordapp.com/attachments/397873516697092116/1338706233070452766/Screenshot_20250210_215431_Chrome.jpg?ex=67ac0ed5&is=67aabd55&hm=d7b768ab85cccf86faf2fefea467ac1f02ce20acde9a2dafd956fec3c87a8189&

someone has experience with https://mfem.org/ ?

What do you guys think of this? https://build.nvidia.com/nvidia/digital-twins-for-fluid-simulation/blueprintcard

(I had the feeling I've seen this image before, just realized tkeskita posted it a while ago 😅 )

Very sceptical, but hopeful that one day it turns into something cool

But that one day is not anytime soon I expect

Will probably suck for CFD engineers a little in the short-medium term when clients/managers don't understand why proper CFD is still required

Also skeptical about using full AI to predict aero characteristics, however it seems they are building a full design environment: > This blueprint is compatible with industry-standard CFD solvers and can connect to third-party tools for meshing and geometry morphing, creating watertight meshes for simulation-ready geometries

Yeah their digital twin stuff is more compelling

Having a surrogate model to generate geometries you can actually solve with CFD is pretty interesting

But an AI aero tool could be a fun toy

Apparently they are not aware of Ansys Discovery

I remember playing with Ansys Discovery a few years ago

Although, I think Ansys Discovery is not AI-based (not sure)

Discovery was (is still ?) LBM based

Nice package! Went through the tutorials and did some solid mechanics stuff.

I can be grumpy again about the absence of "boiling" term in OpenFOAM VoF solvers or complain about me not being able to read on a screen if you want 👁️ 👄 👁️

Jokes aside I am trying to replicate this article : https://www.sciencedirect.com/science/article/pii/S0017931021013363 it is very interesting (it talks about replicating and experimental setup of water boiling in 0-g flight with ansys)

So I want to replicate it in OpenFOAM with interEvaporatingCondensatingFoam (modulo some customization I fear)

Im not using open foam, so I’m not sure, but why is there no boiling term ?

Brb in few to answer, if I don't in 15 mins, feel free to ping me

So I need to correct myself. In OpenFoam, there is boiling. Then about the boiling models, you have to differentiate the boiling methods. First is eulerian "dispersed-dispersed multiphase" and volume of fluid (VoF) "continuous-dispersed" method. In OpenFoam, eulerian methods have the full package (feel free to correct me if I am wrong) in boiling models, I think the RPI model but this one I am not sure. While for VoF it has the Lee boiling model in the company version in "interCondensatingEvaporatingFoam" . The issue is that, at the time, since the Lee model only accounts for mass transfer between liquid and gas, I did not know how bubbles would take shape (changing phase and bubble formation being different). Now I have a bit more idea but I need to try it out to make sure. Basically I have to search for force like shear lift and surface tension, etc as I deal with low gravity simulation (thus no buoyancy). Is it somehow less confusing?

Yeah that makes sense, and that’s quite interesting. Thanks for taking the time to reply 🙂

anyone familiar with the usage of the EDC combustion model version 2016? I am having an issue with simulating ammonia combustion in MILD regime using JHC burner. In addition, there seems to be some bugs in the 2016 model.
