Populations: diagonalization error #5

Open fbonafe opened 5 years ago

fbonafe commented 5 years ago

If molecular orbital populations are calculated, dynamics fails with a diagonalization error: Failure in diagonalisation routine ZHEEVR, unable to complete Cholesky factorization

Conditions when the issue is observed:

SpinPolarisation = Colinear{ UnpairedElectrons = 2.0 } Analysis = { ElectronDynamics = { steps = 1344000 TimeStep = 0.025 Populations = Yes Perturbation = Laser {} EnvelopeShape = Sin2 {} IonDynamics = Yes InitialTemperature [k] = 60.0 FieldStrength [v/a] = 0.1 EulerFrequency = 200 } }

Is this for general structures, or a specific case (could be atoms colliding during the dynamics if so)?

It's for an optimized structure, although I haven't tested it yet for other systems.
