I literally couldnt believe this... I gave #opencode an STL geometry and 2 commands, and it generated this flow solution using my #openfoam installation. It was a completely new session, but I think it must have been trained from my previous work.

Using #opencode I have updated the bouncing-bomb model to include the hydrodynamic forces (lift and drag) on the cylinder, instead of the spring analogy. Here we use representative values for all parameters. I have excluded rotational effects for now. github.com/garcfd/python-…

#UFOLBM with 'experimental' free-slip wall boundary condition - this case ran in 2 hours on @runpod A40 GPU, 96 million cells, 100k iterations.

#UFOLBM with free-slip wall boundary @runpod A40 GPU

its amazing what you can do with #opencode - it has just written a water bounce simulater, and included a readme with the explanation of physcis: github.com/garcfd/python-…

Been dusting off the #UFOLBM solver to check it still works/runs. This case took about 4.5 hours on @runpod single A40 GPU. The mesh is 96 million cells. Here using the bounce-back wall boundary condition, hence the over-separation. Nice car geometry from thingiverse.com/thing:6884252

@fsfarimani I guess you can use #potentialFoam to initialize the solution already, so people would use that if needed.

@garcfd Has anyone tried mixing the two methods? Like using AI to generate the starting points for solutions, "intuitively", and then let the deterministic methods take it from there. This can avoid local extremes, and spead things up, IMHO.

I ran this case in the OF12 #incompressibleFluid solver. It was an interesting experience because I used #opencode to set up the entire case from scratch starting from just the STL file. It took much longer than normal, because of having to feed error messages back into the GUI.

@clark_aviation Britain once thought BIG... what went wrong?

Britain once thought BIG! This is an artist's impression of the proposed Saunders-Roe Queen, a 24 jet engined passenger flying boat, with a capacity of up to 1000 passengers! Clearly something that never made it past the ideas department!

@AleksanderSado1 maybe it thinks there is no separation behind the car so the pressure recovery is very good...?

@garcfd who am i to question such an expert.

it looks like even #Grok can do aerodynamics now - so is there any need for CFD engineers?

@AleksanderSado1 you should ask Grok!

@garcfd why is the pressure high at the back?

I had a go at 'vibe coding' with #codex, to simulate an abritrary STL object floating on waves. All contained in a single python file, which can load in geometry files as long as they are low tri count - available here on Github. github.com/garcfd/floatin…

@skglearning @OCastellarnauD Useful to know the short form in case you get asked at an interview :-)

#VAWT ran in #OpenFoam using @dicehub 'case run' feature - took 31 hours to run, then downloaded the results and did all post-processing on laptop using #Paraview.
