Thanks. I am using a stall model based on the airfoil (at midspan) boundary layer separation.

Thanks, Abdalla. I appreciate it. Best wishes

Hi Bhargav, thanks for your message. A few years ago, there was a post on Boatdesign.net featuring a hydrofoil exercise to validate CFD methods (see www.boatdesign.net/threads/hydrofoil-exercise-to-validate-cfd-analysis.51552/). This was the airfoil used in the exercise so I used for this example. Thanks again. Best regards, Patrick

Thanks for your message. The CAD file can be obtained from the OpenVSP hangar via this link: hangar.openvsp.org/vspfiles/414 Once you have the file, download OpenVSP.org (which is free) and then you can generate a stl file to any resolution and quality. Best regards - Patrick

@@hanleyinnovations Thanks i found it two days ago. now i could know the rest of the geometry except the airfoil. could you give me the coordinate of airfoil? because in VSP only showing the 2d profile without any characteristics available...

@@ppiduniakawasanamerikaerop6084 Thanks for your reply. I do not explicitly know the coordinates of the airfoils. They are already built into the OpenVSP file and will be included with the stl file export. The section can be seen by selecting the wing and then looking at the Airfoil tab in the OpenVSP interface. Thanks again. Please let me know if you have other questions. Best regards, Patrick

@@hanleyinnovations yes i could do that but no information of camber location or thickness. The only way is to make curve fitted of points in the surface and try to export it manually. But thank you!

Hi Esra, Thanks for your message. I hope you are doing well. Stallion 3D is available at www.hanleyinnovations.com. As it is a commercial package, it is not free but available as a yearly subscription. Thanks again. Best regards, Patrick

Hi Erick, I used the wing planform area as the reference area. Thanks for your comment. Best regards, Patrick

Hi Devendra, Thanks for your comments. I hope you are doing well. Stallion 3D is developed as a personal CFD analysis tool for Windows 7, 8 or 10. It does not have a batch function. The software runs interactively and enables users to accurately analyze complex design shapes on an ordinary laptop/desktop computers. Stallion 3D gives engineers a tool to make positive design decisions early in the design process. Thanks again, Best regards, Patrick

Because it is hella expensive for any single person to use.

Hi Buscari, I used 3DFoil for this tutorial. More information can be found at www.hanleyinnovations.com/3dfoil.html. Thanks for your message. Best regards, Patrick

Hi Denton, thanks for your kind words. Best wishes - Patrick

Hi Bryan, your application is very interesting. You design is for high endurance/range. I think that 3DFoil can be used to help with airfoil selection, tip stall and stability. Let me know if you have any other questions - Patrick

Hi Aniket. Thanks for your comments. It works only on the STL format. You can export in this format or convert your model to STL.

Thanks Olajide for your comments. NASA OpenVSP (for aircraft creation) is free. It can be found at OpenVSP.org. Stallion 3D (for the aerodynamics analysis) is not free. More information can be found at www.hanleyinnovations.com. Best wishes.

Patrick Hanley thanks really. please how much does it cost to get the aerodynamic analysis software? and what alternatives are there?

Hi Olajide, Thanks for your follow-up message. The software is available at our website: www.hanleyinnovations.com/stallion3d.html . Please let me know if you have any questions.

Hi Robi, thanks for your comments. My email is hanley@hanleyinnovations.com. I am looking forward to your email. Best wishes.

Hi Bruno, thank you very much. Best wishes - Patrick

Hi Bagrat, thanks for your comments. In this case, only the pressure drag was computed. The friction drag was not included in the l/d computation. Stallion 3D v4 computes both friction and pressure drag.

Hi Hugo, thanks for your email. More information about purchasing Stallion 3D can be found at www.hanleyinnovations.com.

Hi Paulo, thanks for your message. Airfoils by Selig or Eppler are good for flying wings. See the following page: m-selig.ae.illinois.edu/flyingWingAfs/ for a few suggestions. 3DFoil is great to determine an optimum airfoil choice based on your aircraft's wing size, endurance, range and weight specifications.

+tkzsfen Thanks for your question. VisualFoil is for isolated airfoil analysis. So if the blades in the turbine are close to to each other (interacting) then the software will not provide very accurate results.

Hi Philani, thanks for your question. Please visit the OpenVSP page at www.openvsp.org for more information about the operating systems.

+North Lake Thanks

+Dipak Sisodiya Hi Dipak, I am using MultiElement Airfoils version 5.0. More information is found at www.hanleyinnovations.com/mefoil.html

+Mazen Algeneral Thanks for your message. Stallion 3D is available by subscription. More information is at www.hanleyinnovations.com/stallion3d.html . Best wishes.

Aaron Cheng The colors represent the values of the pressure coefficient (Cp). The positive values represent pressure magnitudes that are higher than the ambient (atmospheric). The negative values represent pressure magnitudes that are lower than the ambient pressure.

thanks a lot:)

Hi Rhuth, Thanks for your question. OpenVSP is compatible with Window 7. You can download it at www.openvsp.org. Best wishes.
