cape.pycart.cntl: Cart3D control module

cape.pycart.cntl: Cart3D control module

This module provides tools to quickly setup basic Cart3D runs or a complex Cart3D setup from a small set of input files. Alternatively, the methods and classes can be used to help setup a problem that is too complex or customized to conform to standardized script libraries. A collection of cases combined into a run matrix can be loaded using the following commands.

>>> import cape.pycart.cart3d
>>> cntl = cape.pycart.cntl.Cntl("pyCart.json")
>>> cntl
<cape.pycart.Cntl(nCase=4, tri='bullet.tri')>
>>> cntl.x.GetFullFolderNames(0)
'poweroff/m1.5a0.0b0.0'

An instance of this cape.pycart.cntl.Cntl class has many attributes, which include the run matrix (cntl.x), the options interface (cntl.opts), and optionally the data book (cntl.DataBook), the triangulation (cntl.tri), and the appropriate input files (such as cntl.InputCntl).

Finally, the cape.pycart.cntl.Cntl class is subclassed from the cape.cfdx.cntl.Cntl class, so any methods available to the CAPE class are also available here.
