How to extract a complicated blade geometry using BladeModeler

Hello,
I had a .stp file that I imported into The Blade Modeler. But I am not sure about how to extract the blade geometry for further use in other Ansys software or simply to modify the geometry as required. I have found some videos on youtube that use the CADImport feature by defining a FlowPath and the blade surfaces. Video Link:https://www.youtube.com/watch?v=0Qmm9sKQaFc But due to the complicated shape of the blade, I am not sure how to approach this. Also, I would like to know if there is an easier way of extracting the blade geometry than the process mentioned above. I am including some photos of the blade. If anyone can help me with this, that would be awesome. Last edited by IMK; May 23, 2023 at 10:08. |

What would be your next step with your blade? I guess meshing, correct? Do you think about using Turbogrid? If yes, that can be hard, especially due to the fillets your blade already has...are all 3 blades identical along the rotation axis?

Hey,
I need to extract the geometry and dimensions of this blade reliably, so I can recreate the blade shape using CAD software and make changes to the shape such as changing the chord distribution, thickness, span, and other properties. The shape of this blade needs to be changed frequently and right now there's no easy way of doing it. Also, I do not have the dimensions which were used to create the blade in the first place, that's why extracting the geometry information is so vital for my project. And, yes, all the blades are identical around the axis of rotation. |
