Contacts: Brendan Lyons, Orso Meneghini, Nate Ferraro, Sterling Smith

Short Description

Workflow that allows for automated running of M3D-C1

Keywords

MHD, Stability, Plasma Response, Equilibrium, Linear

Long Description

• GUI for:

  • Starting calculations from new equilibrium files

    • Selecting new equilibrium files

    • Extending profile data beyond separatrix

  • Restarting calculations from an existing OMFIT M3D-C1 directory

  • Loading and modifying C1input namelist

  • Selecting linear calulations to perform

    • Equilibrium, stability, and 3D response

    • Arbitrary toroidal mode number

    • Single- or two-fluid

  • Post-process results

    • Select result directories (remote directories synced locally)

    • Accepts Python and IDL commands

• Automated running:

  • Maps input equilibrium to M3D-C1 uniform mesh

  • Computes equilibrium on uniform mesh

  • Creates shape, n_e, T_e, and T_i plots to check for good equilibrium match

  • Adapts mesh to equilibrium

  • Runs selected calculations

Supported devices

• DIII-D, AUG, KSTAR, EAST, JET, ITER

External dependencies

The M3D-C1 module is self-contained and includes all necessary autoC1 functionality in its LIB/ directory. However, the following external dependencies must be available on the execution system:

• a2cc - Binary utility for converting EFIT a-files to current.dat format

• AUTOC1_ARCH - Environment variable indicating the HPC architecture (e.g., ‘saturn’, ‘iris’, ‘sunfire.r6’, ‘cori-haswell’)

These utilities should be available in the M3D-C1 installation environment on the remote execution server.

Installation notes

The M3D-C1 module no longer requires the external autoC1 repository. All necessary autoC1 functionality has been integrated into the module’s LIB/ directory, and device-specific templates are stored in the TEMPLATES/ directory.
