I was recommended some different tutorials to learn this software, but this was much clearer and concise that the others I was trying to watch. It also uses the updated version of XFLR5. Thank you!
You are welcome Adam, thanks for the feedback and nice comment ☺
Wow! Thank you very much for such a nice explanation. I have watched several videos but they take so much of our time explaining things not much relevant to me. This was a perfect video. Good job!!
You are welcome Apoorv, thanks for the nice comment and feedback ☺
You even did the validation, thanks man.
You are welcome thanks 👍
Really good job. Thank you for this tutorial !
Thanks for the compliment you are welcome
Fantastic Tutorial - really clear and at a good pace
Thanks a lot for the feedback.
Re Validation, Xfoil is very well validated so there is no suprise there. Im looking forward to seeing how acurate the 3d stuff is. PS thanks for this
zabardust profeesor saqib
keep it up
😂
thank you sir . you are such a good teacher
You are welcome, thanks for the feedback and nice comment ☺
Thank you very much, very informative tutorial.
You are welcome thanks for the nice feedback.
My friend said you deserve sloppy toppy for this
Quick tip, if your graphs look like a 3 year old scribble, right click and reset the scale ;-p
I have a problem related to simulating FX 61128 airfoil using XFLR5. I don't get any results on analysis. The question is can I get results for any random airfoil? Or Is it like a predefined set of airfoils which are used for wing analysis?
hi
I am just curious in minute 12.14 where u stated that "viscous effect is not actually calculate here". However there is a viscous function and a display of displacement thickness which through my imagination that is actually a boundary layer.
- With this I mean there are some limitations within xflr5 to calculate viscous effects. That is there is lack of interaction between boundary layer and inviscid flow. Also the estimation of viscous drag.
- Potential methods such as VLM and 3d Panel methods merely interpolate 2d viscous drag from local wing lift that is not good.
- Their is lack of interactive boundary layer loop, which is a coupling method between potential flow and viscous flow on surfaces.
- The effect of the boundary layer is to
modify the geometry of surfaces and to
disturb the inviscid potential flow.
- A loop is therefore needed to reach a
solution that satisfies both the viscous
model and the potential flow model.
- This loop is not implemented in the
panel methods available in xflr5.
- Consequences / drawbacks are:
* The lift is a linear function of the a.o.a.,
unlike with XFoil or with the non-linear
LLT.
* Significant differences in the lift
coefficient predictions at low Reynolds
numbers.
* The potential flow model is only
valid in conditions of limited flow
separation.
Hope this helps, thanks.
@@Simulation-Engineer thank you for ur feedback
I cannot see any graph on operating view. Also the polars I'm getting are not what are shown
Plz check the xflr5 setup in case you missed something and normally you should get similar results, thanks
Hello, I have the updated xflr5 but the graph isn't coming out
Can you explain which graph is not coming out?
How can i install xlr5.
Here is the installer:

@@Simulation-Engineer thanks 🥰
