Solvers
=======

turbigen is CFD-solver agnostic, in that all all pre- and post-processing is
done by native code. Adding a new solver only requires routines to save the
internal grid data to a CFD input file, execute the solver, and read back the
flow solution.

Each CFD solver accepts different configuration options. Solver options and their
default values are listed below; override the defaults using the `solver`
section of the `config.yaml` file.

Turbostream 3
