Detailed Description

Integrate MHD equations using 1D version of the CTU integrator.

PURPOSE: Integrate MHD equations using 1D version of the CTU integrator. Updates U.[d,M1,M2,M3,E,B2c,B3c,s] in Grid structure, where U is of type ConsS. Adds gravitational source terms, self-gravity, and optically-thin cooling.

void integrate_1d_ctu ( DomainS * pD )

1D version of CTU unsplit integrator for MHD

The numbering of steps follows the numbering in the 3D version. NOT ALL STEPS ARE NEEDED IN 1D.
