double_bh#
This test evolves a close binary with initially massive stars toward a double black-hole configuration through chemically homogeneous evolution.
The case evolves both stars, enables tidal synchronization and mass transfer, and turns a component into a point mass after helium depletion. The test terminates after the other component also reaches helium depletion.
How this test passes#
The active test-suite entry expects the output string Terminate due
to helium depletion and checks the final saved model final.mod.
