is the part hollow?
can you delete the surface body and merge the rest of your bodies together?
what settings do you have for internal volumes and volumes without flow conditions?
also, do your initial conditions include a flow velocity?
yes the part is hollow.
I don't quite understand what you meant with "can you delete the surface body and merge the rest of your bodies together" I mean I have 5 stations with cross sections drawn in them. I connected those using surfaces, which I knitted then ceated some thickness to.
I don't have anything set for the internal volumes and volumes without flow conditions. Could this be the problem ? I based this off of the external flow over a sphere example(they don't set anything for the above mentioned) although I can see a problem there since the sphere is a solid body and isn't hollow on the inside.
My initial conditions are set for a velocity of 10 m/s.
hi karim, i'm suggesting to eliminate geometry that isn't important or that might be causing an issue
in the surface bodies folder, rightclick on the surface and choose "delete" to delete the body
use insert > feature > combine to combine all the solid bodies together. ideally i'd suggest filling in the hollow part with solid to see if that helps.
i'd also suggest a CTRL-Q with verification on rebuild enabled to make sure your geometry is good.
just to make sure your flow problem is setup correctly, something you might want to try is delete your solid body(ies) and then replace with just a solid sphere or block. that will confirm that your model is the issue.
if you want to upload your model, i can look deeper.
Okay I'm going to upload the part, it's a little different from what I originally posted in the picture since I went back and tried to mess with it last night but never got to finish it. All I did was get rid of the boundary suraces and use lofts instead. How can I fill the hollow part with solids? I have a feeling that would take care of my problem.
Please find the part attached. Thank you for your time!
knit them together
add a planar surface at the middle/symmetry plane
knit those together and form a solid
mirror the body
once you do that, you should be good to run a flow over it
That worked perfectly. Thanks for your help!
