<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">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.</p>
