# REGCOIL¶

Contacts: Orso Meneghini

## Short Description¶

Run the REGCOIL (regularized NESCOIL) code

## Keywords¶

Stellarator, coils, 3D, optimization

## Long Description¶

This module prepares the input, runs, and postprocesses the output of the REGCOIL code. REGCOIL is used to obtain coil shapes on a fixed coil-winding surface enclosing a specified plasma surface that one would like to reproduce. This is often used in the context of stellarator coil design. The current density on a specified winding surface is chosen to minimize a linear combination of the integral-squared normal magnetic field on the plasma surface and the integral-squared current density on the winding surface. The balance between minimization of coil complexity and normal field error is controlled by the regularization parameter, lambda.

## Typical workflows¶

This module is used to:

• Run REGCOIL

## Supported devices¶

• Any device with an EFIT or VMEC equilibria. REGCOIL also supports a simple circular toroidal geometry scheme.
