// this ini file makes the code as fast as possible, at the expense
// of some loss of fidelity and stability.  The options are done
// with low density nebulae in mind.  The file was developed to
// aid in testing the code in the dynamics case, and the
// approximations are probably ok for that application.
// this file should not be included in any results intended for publication.

// this does not turn on grains - 
// to turn on the very fastest grains, at the expense of the physics, do
// grains single no qheat no physics
