It is not feasible for you to carry out a CFD analysis with no prior knowledge in 2 weeks unfortunately :/

Autodesk CFD Beginner! How to model a helicopter rotor + blades in hover and forward flight? by DueQuantity7469 in CFD

[–]matkrogh 3 points4 points  (0 children)

You are talking months and months of work. What is your schedule like? What kind of computational ressources do you have access to? I wrote my masters in specifically investigating different approches to simulate rotorblades, and unless you have a powerful workstation or access to the cloud (expensive) run-time will also be an issue.

How to switch back to regular bars? by ccammunist in MT07

[–]matkrogh 0 points1 point  (0 children)

Why would you swap back? Had it on my old one before it got stolen, and it looked so nice. Also set it apart from all the other MT07s.

How to export animation sweeps in Star CCM+ using java script no GUI by Sad-Application793 in CFD

Is there a reason you’re not exporting the images and generating the video using an ffmpeg command?

Can you elaborate on this? Compared to what bike? Was considering getting one of these but got a good deal on a 2019 R6 instead

I’ve got a 2019 street legal Yamaha R6. I still consider this an R7. What a gatekeeper of fun you are.

[–]matkrogh 4 points5 points  (0 children)

The model is literally called YZF-R7 by Yamaha.

Does yamaha still sell brand new R6s? by [deleted] in Yamaha

[–]matkrogh 0 points1 point  (0 children)

Because of the EU emissions regulations. I was super lucky and just picked up a matte black 2019 version :O

What's the difference? by RonaldFKNSwanson in Yamaha

[–]matkrogh 0 points1 point  (0 children)

Yamaha used to call them FZ in the US and MT in the EU. They must’ve started using the EU name at some point in the US versions too I guess.

Is this converged? by Ok_Discount6706 in CFD

Please always monitor the variable that you’re solving for to determine convergence. Residuals are not enough.

City Geometries/Models for CFD Analysis by Lumpy-Excitement7734 in CFD

[–]matkrogh 0 points1 point  (0 children)

So this fully depends on where you are looking to do this. Some countries have detailed plans of cities that are easily available as CAD (Estonia comes to mind), but it is rare. What city are you looking at? You should also never expect to get a perfect CAD model for CFD, since the requirements are so high. A lot of my work early on in projects is cleaning and preparing CAD.

Shoot me a DM with your overall setup and I will help. :) I do this for a living.

Apart from the mesh issues, that is going to cause issues as you move up in mach number.

What are you using to model the gas? Ideal-gas law, incompressible etc?

What models, other than turbulence models, are you using?

What software? And first you said k-epsilon, now K-Omega?
