jdm aks eigenmode solver
I see in its manual, we should require more modes than needed to ensure accuracy, because solver may give poor accurary for higher order modes.
But one time, to confirm the convergency of results given by the solver, I increase the density of mesh step by step and inspect changes.
To some extent, I think the mesh is not very dense, just 900000+ cells, but even some lower modes have poor accuracy (marked with * by CST).
Anyone encountered such a situation? What's the reason?
Thank you for ur attention!
