Hey! I'm new to this software and try to understand how it's work by watching your videos. But i encountered some anomaly. I've followed every steps on your vid but when i did a simulation it says span pos= xxxxx re xxxxx cl xxx is outside the flight envelope. Is there anything i could do to overcome this problem? Thanks for your help!
Hey, I'm part of a DBF team trying to do some analysis. I'm used to the old version where you can check and uncheck all the different analysis it does in a batch to check out the Cl curves for a specific Reynolds number. New version doesnt seem to do this, and for the life of me I cant figure out how to get it to work! You mentioned using "show all op points" for the selected foil up top, but I've done e that (also tried hide all polars and then tried show associated op points) and it didnt seem to do anything.
Are those figures you have on the Note at the right hand side at the beginning of the design for the wings calculated by yourself or they are just existing figures for your desired cessna wing design. I mean the figure for m, V, h, mu? Are they an already existing figures for the cessna you choosed to design?
On upper side, there are few symbols. After these symbols, there are 3 successive windows. Click on 3rd windows and u will get a list of Reynolds numbers. Click on each one by one, and change the colour on the analysis window.
I replicate your process to learn and check the results. But I encountred a problem and result did not pop-up. Shown problem is "outside the flight envelope". I little search on internet people suggest changing the Re number but its not make sense because I did what you did so why did I encountered this problem ? PLEASE HELP..

Very helpfull video! Nice work and thanks for sharing :)
thank you so much for this!
you have helped me so much for my final year project
Great work. Very useful . zmz

Hi! Can I get the CL_máx or stall angle of the wing or is it only obtained for the airfol?
Merci !
thanks u

In the plane analysis, are the CL and CD values shown below average values for the whole wing?
how i can get loads acting on each rib station? video was really helpful.
good question!
why did you choose the Ring Vortex method? and what are the differences between VLM and this one?
The author was just vomiting out from something he mugged !!
When I do a batch analysis, all the lines in the graph are the same color. How to change this?

Hi guys, when running an analysis I cannot input values higher than Re 900000, do you know how can I solve the problem? Thanks for your help
you can, just erase it all and type in again
hello, how do you display the skin friction coeffcient please?
In which university are you a profesor?
