Eigenvalue Solution Changes as Mesh changes
Asked by
Houdong Hu
Originally I try to use adaptive mesh to solve some eigenvalue problems. But the results I get are far from the real values. Finally I test it with 1D harmonic oscilator and uniform mesh, and I find the calculated eigenvalue is proportional to the mesh size.
I also test the demo examples in dolfin/
When I run "demo_eigenvalu
If I add "mesh=refine(mesh)" and run it again, I get the result is about 6
Is the eigenvalue solution should be independent with the mesh size?
