Features

The w7x package provides convenience methods for Magnetic Field evaluations around the stellarator Wendelstein 7-X. The zen of the package (in addition to the zen of python) is the following: * be intuitive * Tell the user what he does wrong (the web services often fail without a clue for the user). * Provide proper defaults for your functions.

The module includes handy wrapper methods for the following web-services: * FieldLineTracing (see “http://webservices.ipp-hgw.mpg.de/docs/fieldlinetracer.html”). Namespace: w7x.flt * VMEC (see “http://webservices.ipp-hgw.mpg.de/docs/vmec.html”). Namespace: w7x.vmec * EXTENDER (see “http://webservices.ipp-hgw.mpg.de/docs/extender.html”). Namespace: w7x.extender

The package provides explicit classes for the osa types of the web-services provided. The main starting point for the use of services is the Run() class e.g. `python import w7x run = w7x.flt.Run() lcfs_points = run.find_lcfs() # returns one point on the lcfs ` Most services are started from this class.

We utilize the tfields module in order to take care of proper coordinate transformations since some web-service tools need special coordinate systems.

Note

If you want to use the divertor or baffle evaluator (for example see diffusion mapping example<https://gitlab.mpcdf.mpg.de/dboe/w7x/tree/master/examples/diffusion_mapping.py>, i.e. build an evaluator object like so:

divertor_evaluator = w7x.evaluation.TracerEvaluator.from_loader(
    w7x.Defaults.Paths.divertor_upper_tiles_template_path)
