timing

This test checks the counter and timing routines with a 1.5 Msun, Z=0.02 metallicity model.

This test case has 2 part2.

• Part 1 (inlist_zams) builds a 1.5 Msun, Z=0.02 metallicity and evolves it to the zero-age main sequence.

• Part 2 (inlist_timing) continues the evolution until the central mass fraction of hydrogen drops below 0.5. To get a counter and timing breakdown the star_job namelist parameter first_model_for_timing=2 is set. At the end of the run, various counters and timings are written to the terminal:
