Geometry Generation Fail

AmandaMBF · July 26, 2012, 21:52

Good Night everyone,

I'm trying to do a fluid simulation over an Eppler 423 airfoil. I'm following this tutorial https://confluence.cornell.edu/displ...oil+-+Geometry.
I could generate the curve, the surface, the grid and the grid surface. But then I have to create two lines, one horizontal line dividing the grid in half and one vertical line dividing the grid in half. I can create the horizontal line but I cannot create the vertical line. When I try to generate the line by selecting the sketch and generating the curve I have the error: "Boolean operation failed".
Does anybody know how can I fix it?

Thank you

Hi,
Could you specify what software you are using?
It looks like your problem is more geometry/meshing related, therefore maybe you should post in the appropriate section of the forum to get an answer?

Hello Marion,

Yes it is geometry related. I'm new on this forum so thanks, I'll post it in the apropriate forum.
By the way I'm using Ansys Workbench - Fluent to do the simulation and I'm creating the geometry there.

Thank you very much,

Amanda
