[CP2K-user] [CP2K:19525] Cholesky decomposition failed. Matrix ill conditioned ?

[Jürg Hutter]

Hi

your SCF calculation never converged. The error you see follows from there.
First try to get a converged wavefunction before starting an optimization
of geometry and cell.

Additional hint: use MOLOPT-SR basis sets also for the lighter elements, it will
speed up the calculation

regards
JH

Hi CP2K forum,
I'm trying to optimize a composite with CELLOPT and I'm getting the following error " Cholesky decomposition failed. Matrix ill conditioned ?" can anyone help me out here ?.. I'm enclosing input and output here

                                                           thanks in advance
