@@cillianthomasengineering Thank you! It would be immensely helpful for those making the switch from Fluent to Openfoam, and possibly later on could you do a tutorial for dynamic meshing using the same setup
I really like this vide, appreciate your effort and time to create such useful video, please make next video on " how to improve the mesh quality such as aspect ratio, orthogonality, and skewness. Thank you
Hi, I found this video really helpful. However, i have encountered one issue. I am running ANSYS R19.2, i followed the exact same steps shown in the video and although i get practically the same results for Drag Coefficient and pressure coefficient, my lift coefficient is about 30% less than the one you find. Any suggestions?
Thanks for the very useful tutorial. Just a question: is it possible to compute the c_d and the c_l as output parameters without being costrained to change the force vectors on report definitions every time? I did parametrize velocity components as input parameters and drag&lift coefficients as output parameters, but I can't change their direction definitions (wich, as you already know, change for every angle of attack). Thank you SO much 🙏
Hi Cillian, I watched your video on the "3D Aerofoil Tutorial in ANSYS FLUENT - NASA Onera Wing," but I'm encountering issues with the preference method you suggested. Whenever I switch from CFF to legacy, I face difficulties opening CFD. The error message I received is: "Application error(s) occurred in CFD-Post. The run 'RunSteady' in simulation 'Simulation' contains transient output, but no output files were defined." However, when I switch back to CFF, CFD post opens successfully, but I am unable to visualize the pressure coefficient on the Y-axis in CFD post. This data is crucial for validating my ongoing research work, so I would greatly appreciate your assistance with this matter. I look forward to hearing from you soon.

hello the video was so helpful thank you again for the great work and without your beatiful smooth way of explaining i dont think i would have understood this simulation anywhere else, one quick note tho, i have went and took a look at the paper from which you got the experimental data to compare with the simulation results and have realized that they used a 24 inch chord which is equal to about 0.61 meters but in the simulation you put in 1 meter chord i think thats why your drag coef and lift coef have that much high of an error(even though its considerdedvery low when you consider the fact that its just a simulation compared to experimental data). thanks adain for this wonderful video
Hi Cillian! If my chord length is 0.25m instead of 1m, does that mean that the reference value for area needs to be 0.25m^2 or keep it as 1m^2? Thanks!
Absolutely amazing! This was a real class! I need to watch again and take notes to absorb all this knowledge you put into the video. Do you have any material indication about fluid simulation for starters?
