[Nek5000-users] Solving the Poisson equation in Nek5000

[nek5000-users at lists.mcs.anl.gov]

Hi all,


I am trying to solve an equation similar with the Poisson equation (\nabla^2 \phi = A) in Nek5000, but I do not know which subroutine can do this work properly.


The variable \phi in computational domain has Dirichlet boundary conditions (e.g. A = 0). I think maybe the subroutine "hmholtz" can help solve this problem, but I have no idea how to set the commands, including setting of the boundary. Is there anyone having some idea? Any suggestion is welcomed. Thanks for your time.


Best regards,

Zhe
