I was using thickness =-1 I think it does definitely need a finer mesh close to the aerofoil surface. The 2D mesh generated on the surface is OK, it's relatively fine because it follows the CAD file in which the surface is divided into fairly narrow faces. However as the overall fluid mesh density i...

I don't think I'm getting anywhere, I just can't see why this won't work. I've simplified my wing down to one single section and thinned out the points on it (imported from CAD as a brep) https://www.avianonline.co.uk/userfiles/mesh1.png I've tried coarser and finer meshes (I've attached the coarser...

Hi, no the it is only perspective that is making the aerofoil look full, it is empty and there definitely is a boundary face called "aerofoil_surf" on the wing surface. This mesh has a very high density at the stagnation point of the aerofoil, I wonder if that is throwing off the boundary ...

Actually, it seems to work fine for me for primitive shapes (cube and sphere created in the Geometry workbench), so it must be some problem with my wing shape geometry. I'll try breaking it down into simpler units and see which ones work.

Also @Guillaume THIRIET , have you successfully used this boundary layers insert method at all? If so then can you share a mesh that it works on and I can see if it works for me on the same mesh?

Thank you for your help. I did find the example user mesh file at the location you suggested and I used this as a template. However it makes no difference. Again it takes longer over the mesh preprocessing as if it is doing something, but no boundary layer elements appear. The reason I exported .cgn...

I'm trying to follow this tutorial for inserting boundary layer elements: https://youtu.be/VGpiWwZYrH4 I didn't know where to download the car from, so I was using a wing. My first problem was was that my /SRC folder is completely empty, there is no EXAMPLE or REFERENCE folder as shown in the video,...

Thank you for all your help. So it seems I have finally got it working! Code Saturne v8.0beta (installed without Scotch), and CFD extensions main branch, and it does now work. Hooray! Now I have it installed I just have to remember what it was that I wanted to do with it, it seems so long ago..... :...

I've got Code Saturne v7.0.5. When I used the v7.0 of the CFD extensions then when I run salome_cfd then I don't have the CFD extensions icon in the menu and get this error in Terminal as soon as I start it: ************************************************************** Warning: module CFDSTUDY is i...

Hi, I've tried installing again in a separate build directory. Some improvement, I don't get the immediate warning on the command line and I do have a CFDSTUDY icon in Salome (hooray!). However when I click the icon then I just get an error message when it fails to load. What do you mean by: You did...
