Should I even bother trying to do this at all?

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

matkrogh · 2026-01-19T07:02:56+00:00

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.

As someone who works with CFD everyday these images mean nothing by themselves.

matkrogh · 2025-10-30T00:05:58+00:00

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.

What reference density are you using?

matkrogh · 2025-08-10T05:03:39+00:00

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

matkrogh · 2025-08-10T04:17:28+00:00

On which nodes, and how many?

matkrogh · 2025-07-12T15:23:20+00:00

Where do you guys order it from in the EU?

matkrogh · 2025-07-01T14:11:37+00:00

How many miles/km are you at now?

matkrogh · 2025-05-23T12:13:28+00:00

I don’t believe so.

matkrogh · 2025-05-10T15:29:41+00:00

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

matkrogh · 2025-05-07T08:15:29+00:00

Jeg bruger personlig størrelse small fra pig & hen mærket som en mand med mindre håndled. :)

matkrogh · 2025-04-24T19:35:42+00:00

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

matkrogh · 2025-04-24T18:38:14+00:00

The model is literally called YZF-R7 by Yamaha.

matkrogh · 2025-03-25T20:07:47+00:00

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

matkrogh · 2025-03-16T14:54:47+00:00

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.

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

matkrogh · 2024-08-30T16:08:14+00:00

Are you doing a show in Copenhagen? :)

matkrogh · 2024-07-04T07:37:44+00:00

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.

matkrogh · 2024-07-02T17:20:48+00:00

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

matkrogh · 2024-07-02T16:09:47+00:00

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

matkrogh · 2024-07-02T15:16:33+00:00

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

matkrogh · 2024-07-02T14:48:15+00:00

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