It says that your generated mesh has some vertices, edges, or else that does not belong to any cell. I suggest you have a look at the generated mesh to see if you can spot such an artifact, and then figure out how to drive gmsh to not have such a thing.

Subject: [firedrake] problems with importing a mesh
 

Hello,


I have created a mesh of an oceanic basin that I have triangulated with gmsh.  Finally!  I am very excited to solve for the wind-driven gyre solutions with this new mesh (as I discussed back in March at the workshop), unfortunately, when I try to import the mesh I get the following:


mesh = Mesh("test3.msh")


ValueError: Provided mesh has some entities not reachable by traversing cells (maybe rogue vertices?)


Any ideas as to what I might have done wrong and how I can fix this?


Cheers, Francis
