Dirichlet boundary conditions #5

Closed negf closed 2 years ago

negf commented 6 years ago

Hi,

Is it possible to define the values of phi on the boundary when using Dirichlet boundary conditions ?

Hi. No, unfortunately it is not possible.

Hi,

This is a follow-up of negf's question. Does this solver only handle homogeneous Dirichlet and Neumann conditions (i. e. phi = 0 and dphi/dn = 0)? Is it possible to implement non-homogeneous boundary conditions?

Thanks

Helo, this is not possible with the FFT method.
