High Cambered Aerofoil Meshing Problem (Workbench)
1 Attachment(s)
Hi! I've been following this tutorial:
https://confluence.cornell.edu/displ...Airfoil+-+Mesh for creating my mesh around this specific aerofoil, however due to it's high camber and asymmetry instead of using the Mapped Face meshing technique I applied the Multizone Meshing one where the following are my constraints: Mapped mesh type: Hexa Free mesh type: Not Allowed However the following image shows the discrepancies from just below the bottom edge of the aerofoil to the centre line x-axis. How can I resolve this and any another of the errors that have appeared (such as overlapping geometry)? Dropbox of files: https://db.tt/VIRzWkbe Any help is truly appreciated! Kind regards, Ele |
Here is a thread about the same topic.

Hi, for the geometry setup I used this particular tutorial: http://www.mne.psu.edu/cimbala/Learn...ial_Airfoil.pd
Which I believe follows the 'Form new part' as you suggested in that thread? When you suggested to 'merge' the two sections how would I go about that? Thank you for your reply!! |

I'm really new to this so please could you explain in a little more detail?
The only boolean command I used during Design Modeler was to remove the airfoil from the fluid volume. Thanks once again. |
Then you already know how to do it.
Only this time, you have to unite the face that is causing the distorted mesh with the adjacent face. There is even a picture in the linked thread. Please note that in the cited thread a completely different approach was chosen in the end. |
I have united them using a boolean however when I ten try to open it for meshing I am only left with the bottom left quadrant and the aerofoil! (The other 3 quadrants have disappeared even though they still appear in design modeler)
|
Post a screenshot of the model tree in Design Modeler before you proceed to the meshing application.

Thank you.

My bad.
I forgot to mention that we need screenshots where we actually see the relevant parts of the model tree.;) Expand the geometry section and post at least 2 screens where you clicked on each of the 2 "parts" so we can see its details in the details view. |

Ah sorry about that, is this good enough? I deleted the boolean to show you the two specific parts.
|
I dont feel like we are going to solve the problem this way. For example, I have no idea where the line body is coming from.
I recommend you start over again and use the approach outlined in the linked thread ("bottum up", separate sketch for each of the four planes). |
