## Agenda

1. Any questions or items to raise for discussion (please add below)
2. [Actions from last week](https://github.com/usnistgov/am-dt-modeling/blob/main/resources/meetings/DT%20AM%20Meet%202025-03-19.md#action-items)
4. Issues with Adamantine and using TorchDA
    - Why do I want to do this?
        - Control the parameter updates 
        - Have a wide range of parameter updates
        - e.g. have a temperature dependent material parameter as update
        - control the H function (state -> observable)
            - no provision for this currently in Adamantine
        - Data assimilation should be programmed in high level language due to the many customizations that are required
    - Hoping to use the restart mechanism but restart files are just serialized dumps of state. 
    - Not reasonable to read/write C++ update serialized dump from within Python
    - For now test Adamantine / TorchDA with single runs without continous updates
        - This is adequate for feasiblity study
    - Other options for TorchDA / Adamantine coupling
        - Update Adamantine to allow initial imposed fields
            - lose current mesh refinement
            - many drawbacks with this approach
        - Update Adamantine to restart from VTK files
        - Update Admantine to read updated fields from files in the same place where current DA is used
        - Call Python from Adamantine C++ and use in place of current DA 
        - Use Adamantine as a C++ library from Python
        - Just use current DA capability
        - Just use Adamantine for paramteer estimation
