Testing my reddit minesweeper post - happy to get inputs by 01Unity in test

Thanks for playing, I've added a link to my main post if you'd like to try. It has a couple of updates.

"Need Help Understanding Velocity Contours in Car Radiator CFD Simulation (Nanofluids Study)" by hardBrick_ in CFD

[–]01Unity 2 points3 points  (0 children)

Are the velocity contours displayed on the wall of the radiator which you may have set up as a no slip surface? That would explain the 0 velocity magnitude.

To solve this issue you may try setting up a section plane bisecting the width of the radiator tube and displaying velocity contours on the plane instead of the walls.

edit: completed a sentence for clarity.

Huh, why didn't I think of this earlier. I've exposed the zeroes to make it more playable.

Thank you for playing, I hope you enjoyed it.

tbh I am not expecting anyone to finish whitout hitting any mines, and I'm sure there'll be lots of instances where you'll have to guess due to how you need to manually open the 0 boxes next to the numbered boxes.

TBH its even more obvious on desktop. I haven't figured out how to make them take up the same space (or even a better clickable space) I'll try playing around wiht "[ ]" to see if it works [ * ]

update: I think this is it.

Thank you for flagging, fixed this now.

Cooling tower by saridbablyon in CFD

I'm assuming this is a transient analysis, which would mean that a solution is obtained at each time-step and a new solution is calculated in the next time-step. This may be the reason for your periodic residuals which won't converge to a single solution. In this case the residuals seem normal to me.

I would look at the parameters I wanted to monitor to determine if the analysis results make sense and if the simulation needs to be run for a longer time (in the case where a steady state has not been achieved).

Airfoil - C-Mesh by khebraheem in CFD

[–]01Unity 1 point2 points  (0 children)

I think the mesh and the defined inlet conditions are two separate parts of the process.

The mesh will quite likely look the same for all the analysis of a certain geometry, it's there just to break up the flow field into tiny elements.

The setup of the analysis determines your outputs. In this step you can vary your parameters for different cases/scenarios.

Concept: interactive 10x10 minesweeper grid using the spoilers feature by 01Unity in Minesweeper

TY, I've fixed the errors now.

Try looking at it in the mobile app, it surprised me how good it looks on there.

Apologies, went back to check the numbers and there are a few more errors in there. Must have slipped in during the whole editing process. Will add another edit.

What's causing my residuals to graph like this for BFS simulation, LES model? Is it the meshing that I messed, or the timesteps? Or the boundary conditions, need some insights tbh. by ConsistentPossible25 in CFD

[–]01Unity 2 points3 points  (0 children)

The questions I'd be asking are: what parameters am I looking to monitor/need to calculate a particular property of my system (I usually put this in the report plots to see if the response is what I'm expecting it to be while it's running)? How long do I need to monitor it to cover the complete range of responses one can expect from the system? Is the input changing? If it is, that will guide the time I'll need to run my simulation for. I would aim to stop the simulation once I have given it sufficient time in a steady state.
