[d3]Is EVP support 2D eigenproblem like BiGlobal stability analysis? #217

Closed demonh6 closed 2 years ago

demonh6 commented 2 years ago

I'm trying to solve the eigenvalue problem of schrodinger equation of two-dimensional stationary harmonic oscillator by Dedalus. But I ran into difficulties and didn't find similar examples to refer to. I wonder if v2_master and v3_master can solve BiGlobal Problem. Thanks for answering me!!! Here are the errors I encountered In v2_master: NameError: name 'dy' is not defined. Did you mean: 'dx'? (How to make EVP dealing with dx and dy at the same time) In v3_master: solver.solve_sparse(solver.subproblems[0], 10, 2) ------NotImplementedError Another multi equations problem (such as NS equations) In v3_master: INFO :: Building subproblem matrices 1/1 (~100%) Elapsed: 1s, Remaining: 0s, Rate: 9.8e-01/s Traceback (most recent call last): ------RuntimeError: Factor is exactly singular
