## Geometry Specification

##

#### Subroutine: initbndry

#### Namelist Parameters: rzero, rmax, modelbnd, ashape, bshape, cshape,
eshape, xshape, nbndry

TOQ allows either for the outer shape to be parameterized or for the
shape (as well as rzero and rmax) to be read in from a dskeqdata file.
The choice is given by the **modelbnd** namelist variable:

- If
**modelbnd=1** then use the parameterizations described below,

If **modelbnd=2** then use the dskeqdata file.

Aspect ratio is set by rzero=Ro and rmax=a.

### Shape Parameterization

TOQ allows five different ways to parameterize the last closed flux
surface. The parametrization chosen is given by the **ishape **variable.

### ishape=0 Circles

### ishape=1 Bean Formula

### ishape=2 Dee Formula

### ishape=3 Inverse Dee Formula

### ishape=4 Bondeson's Dee Formula

### ishape=5 Dee Formula for Low Aspect Ratio
