I'm trying to mesh a rather complex STL-file. When i put this file in the middle of a "windtunnel" where the boundaries of the surrounding box are far away from the file, everything works fine and the caluclations seem to be realistic.
But in my case, it is necessary that at least one face (inlet patch) touches the stl, because I want to simulate the flow inside of an airfoil.
But when I make these adjustments I get the following error whilst running snappyHexMesh:
(I reset the swap size of my computer to ten times of the original size)
It doesn't matter how long the calucation takes. It simply should work!
I saw your post a while back, but only now have I been able to log in and try to answer you:
thanks for your reply!!
I tried the same case on a computer with 24GB of memory and it worked :)
but thank you for your hint using featureEdge!!
And I also thought about just meshing the inside of course, but the problem is that the stl-file of the wing is hollow and the solid layer is very thin. So snappyHexMesh won't stop when reaching the boundary of the airfoil.
Or is there any option which handles this?
You can do that with the first step of refinement (ie, bounding box). Practically you need the cells in that area to be smaller of the solid thickness to let the snapping part to work and understand which cells have to be eliminated and to which side snap onto.
I'm going to try this!
