Solving Gambit Meshing Errors on Helical Tube

[Vnt666Skr]

I am quite new to using Gambit and I having problems with mesh generation for my helical tube. I split the entire volume into 4 smaller volumes. Now, when I try to mesh each one of them errors start to crop up. These are the errors associated with the meshing of each volume

1. independent loops of swept faces on volume 2 had mismatched intervals
2. natural source face for projecting volume 3 could not be found
3. the intervals would force the mesh to cross itself could not be meshed using cooper scheme
4. check the interval assignments for correctness volume 7


One of the volumes[shows 'meshing face 4' and it never ends] take very long to mesh and the process eventually terminates saying not enough memory.

Pls help me out.!

Here's the screenshot of my model in Gambit

There are several potential causes of the errors you're seeing. First, it is important to ensure that all faces on a swept volume have matching intervals. If the intervals do not match, this can lead to the error you saw with Volume 2. Second, when meshing a swept volume, Gambit needs to be able to find a "natural source face" to project mesh onto. This is the face that Gambit will use as the starting point for projecting mesh onto the other faces of the swept volume. If the natural source face cannot be determined, you will see the error you saw with Volume 3. Third, when meshing a swept volume, the intervals assigned to each face must not overlap, or else the mesh may cross itself. This is the likely cause of the error you saw with Volume 7. Finally, if one of the volumes is taking a long time to mesh and eventually fails due to insufficient memory, this could be caused by a number of things. It could be because the geometry is very complex (e.g. many curved surfaces) or because the intervals are set too small. The best way to troubleshoot this issue is to try meshing the volume with larger intervals. If this does not solve the problem, then the underlying geometry may need to be simplified in order to generate a successful mesh.
