Issues with AdaptiveDampingFactor in X-2025.06 version

[evansjc]

Hello,

I tried setting the damping factor of my LCAO calculator to AdaptiveDampingFactor as shown below.

iteration_control_parameters = IterationControlParameters(
    max_steps=200, damping_factor=AdaptiveDampingFactor
)

However, when I try to tun the script, AdaptiveDampingFactor does not seem to be recognized. I get the error below.

NL.ComputerScienceUtilities.Exceptions.NLValueError: The damping factor given to IterationControlParameters must be a floating value - e.g. 0.3 or 1e-6
NL.ComputerScienceUtilities.Exceptions.NLValueError: The damping factor given to IterationControlParameters must be a floating value - e.g. 0.3 or 1e-6

Is AdaptiveDampingFactor not supported anymore?

I would appreciate any suggestions on how to deal with this issue.

Thank you!

Hi, Why would you choose it as adaptive instead of default 0.1 or below?
Incase you are facing convergence issues try it as 0.01

I am facing convergence issues. I will try 0.01 and see if that helps.

Thanks!

If 0.01 also gives convergence issues.. try 0.01 or 0.02 with history steps reduced 12
