SIMSOPT - New Coil-n-Currents, Derivatives, and stage II coil optimization

Courtesy @florianwechsung, this release introduces new Coil, Current, and Derivative classes and allows for stage-II optimization

  • A new Coil class that represents a Curve and a Current. A list of Coil objects is now passed to BiotSavart (instead of separate curves and currents in the past). These objects are built on top of the new graph framework

  • A new Derivative object is introduced, that is essentially a dictionary containing the partial derivative of a scalar objective wrt to all the Optimizable objects (with >0 DOFs) that it depends on.

  • Simsopt can now solve the Stage II coil optimisation problem.

SIMSOPT - v0.4.2 Released

This release introduces

1) The ability to compute fieldlines as well as particle trajectories using the guiding center approximation. Credits to Florian Wechsung. 2) A quadratic-flux minimizing surface solver, defined as the minimizer of the objective function

f = int d^2 x (B \cdot n)^2/int d^2 x B^2

at fixed flux surface label (e.g., volume, area, or toroidal flux). This optimization problem can be solved using a 
penalty formulation with LBFGS or with the SLSQP constrained optimization algorithm. Much of the code was 
modeled after the Boozer surfaces.

SIMSOPT - simsopt v0.2.0

This release introduces some additions and bug fixes for majority of modules in simsopt.

Changes introduced: 1. New class for Reiman magnetic field (see section 5 of Reiman, Greenside (1986), "Calculation of three-dimensional MHD equilibria with islands and stochastic regions", Computer Physics Communications 43 (157-167)) is added by Rogerio. This field has the advantage of allowing an exact calculation of the island width which can be used for island width optimization (example: https://arxiv.org/abs/2102.04497). 2. Faster Biot-Savart code by Florian 3. A simplified logging interface is introduced by Bharat. Logging can be enabled by using the following two lines in your driver script: python from simsopt import initialize_logging initialize_logging(filename="simsopt.log") # Filename option can be omitted in which case the default name is default.log 4. Some modules are rearranged. 5. Top-level imports for important classes are introduced. 6. Automatic linting script implemented by Florian. Before you submit your additions/changes to simsopt as PR, please run the run_autopep script. Requires autopep8 and flake8. 7. A new exception class to handle failures in objective function (credits to Matt Landremann). 8. Bug fixes. 9. Improved documentation.

SIMSOPT - Boozer surfaces in simsopt

This release introduces boozer surface and computation of aspect ratio of surfaces and some major refactoring of surfaces-related code.

Major changes:

  1. SurfaceXYZFourier surfaces are introduced, where (phi, theta) correspond to the Boozer angles on the surface, by solving a nonlinear least squares problem in boozersurface.py.

  2. minimizeBoozerScalarizedLBFGS solves a scalarized constrained optimization problem using LBFGS, where min 0.5* || f(x) ||^22 + 0.5 * constraintweight * (label - labeltarget)^2 +0.5constraint_weight * (y(varphi=0,theta=0) -0)^2+0.5constraintweight * (z(varphi=0,theta=0) -0)^2 where || f(x)||^22 is the sum of squares of the Boozer residual at a set of quadrature points. The final two terms in the objective function are boundary conditions to ensure that the parametrization of the surface is unique.

  3. minimizeBoozerScalarizedNewton solves the same scalarized constrained optimization problem as above, but instead of LBFGS, Newton's method is used.

  4. minimizeBoozerConstrainedNewton solves the full constrained optimization problem using Newton's method. min 0.5*|| f(x) ||^2_2 subject to label - labeltarget = 0 y(varphi=0,theta=0) - 0 = 0 z(varphi=0,theta=0) - 0 = 0 The user is free to choose either a geometric constraint, e.g. area, or a toroidal flux constraint. objectives.py is split into coilobjectives.py and surfaceobjectives.py

  5. Computation of aspect ratio of surfaces using the VMEC definition of aspect ratio is done in the Surface.aspect_ratio.

  6. New capability of computing cross-sections of surfaces at a given cylindrical angle. This is done using bisection in the Surface.cross_section.

  7. An implementation of SurfaceXYZFourier.toRZFourier using Surface.crosssection. This is done by computing cross-sections of the SurfaceXYZFourier object and then fitting a SurfaceRZFourier to those cross-sections.

SIMSOPT - Surfaces in simsopt.geo

Major changes:

  1. simsopt.geo subpackage introduces a surface class, and two specific implementations SurfaceRZFourier and SurfaceXYZFourier. The interface is closely aligned to the Curve classes, i.e. s.gamma() return an array of dimension (numquadpoints_phi, numquadpoints_theta, 3), and there are implementation for tangential derivatives and derivatives wrt to the dofs.
  2. The two curve classes are renamed into CurveXYZFourier and CurveRZFourier for consistency.
  3. Magnetic flux is added to Biot-Savart computation.
