Rdmft - Including Preconditioning
We tested the application of the preconditioner for the cg routine of rdmft. In all examples it converges faster with all the standard preconditioners (filter, jacobi, poisson). Filter seems to be fastest and is the default now.
The CG minimizer of RDMFT supports now preconditioning.
- I have checked that my code follows the Octopus coding standards
- I have added tests for all the new features added in this request.
