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.
| erhsFull | threshold on equation errors for applying full corrections in relaxation solution |
| logEps | log 10 of convergence tolerance |
| delta | desired average fractional change in variables per step |
| nitx | max number of iterations before restarting with a smaller step |
| nRestart | number of successive timestep reductions before giving up |
| scalePow | when the error is larger than erhsFull the corrections applied are scaled by (err / erhsFull)^scalePow |
| nitCapDt | if a step takes more than nitCapDt iterations to converge the timestep is not increased even if the actual changes are smaller than delta |
| fDtMax | maximum increase in dt allowed on a single step |
| showTiming | print profiling information to the terminal |
