StarCtrl

Control parameters for stellar evolution, setting convergence criteria, governing timestep control, and output options.

The function of each variable can be displayed as a "tool tip" by letting the mouse linger over the variable.

erhsFullthreshold on equation errors for applying full corrections in relaxation solution
logEpslog 10 of convergence tolerance
deltadesired average fractional change in variables per step
nitxmax number of iterations before restarting with a smaller step
nRestartnumber of successive timestep reductions before giving up
scalePowwhen the error is larger than erhsFull the corrections applied are scaled by (err / erhsFull)^scalePow
nitCapDtif a step takes more than nitCapDt iterations to converge the timestep is not increased even if the actual changes are smaller than delta
fDtMaxmaximum increase in dt allowed on a single step
showTimingprint profiling information to the terminal
