Generated initial model for primary WD of mass 0.9 solar masses, central density 1.574e+07 g cm**-3, and radius 6.747e+08 cm. Generated initial model for secondary WD of mass 0.9 solar masses, central density 1.574e+07 g cm**-3, and radius 6.747e+08 cm. Generated binary orbit of distance 1.781e+09 cm = 1.190e-04 AU. The primary orbits the center of mass at distance -8.903e+08 cm = -5.951e-05 AU. The secondary orbits the center of mass at distance 8.903e+08 cm = 5.951e-05 AU. The initial orbital period is 30.543687 s. The initial orbital speed of the primary is -1.831e+08 cm/s. The initial orbital speed of the secondary is 1.831e+08 cm/s.
