Hello to everyone.
can someone please help me with a question in Ansys?

I am student and i am working in mechanical APDL. So, i would like to connect these 3 models (airfoils, see attached foto) as a single volume.

I am trying to design a blade with different scale along it. I have already design the airfoils with the specific scales and i can't connect them in order to make my blade model.
I think that extrude command will be a solution but i don't know how i can connect the different airfoils.
Any idea?

Thank you in advance

Hi Dimitris,

This an easy thing to do with any CAD software, like a 1 button click in Ansys Spaceclaim using blend option.

But if you want to do it in APDL, you have to adopt a bottom-up approach. I would recommend to create guide curves between the 3 different leading edges points and trailing edges points. Once you have those guide curves you can use the “VDRAG” command to create a volume.

Have fun

Thank you for your response.

I know that i easily can face this kind of problem in a CAD programm but i must to design my model in APDL.

I didn't try your proposal because i used the command "L, keypoint1, keypoint2" to design lines between two keypoints. So, in a .txt file i wrote the specific keypoints and i designed the lines. I found this as an easily way to draw areas after the lines and a volume after all.

The problem at this time is that i can't design areas according the lines even if i found the command "AL" which is used for this condition. The error "lines not listed for AL command" appears and for the time i can't overpasss it.
