Detailed Description

Integrate MHD equations using 1D version of MUSCL-Hancock (VL) integrator.

PURPOSE: Integrate MHD equations using 1D version of MUSCL-Hancock (VL) integrator. Updates U.[d,M1,M2,M3,E,B2c,B3c,s] in Grid structure. Adds gravitational source terms, self-gravity.

void integrate_1d_vl ( DomainS * pD )

1D version of van Leer unsplit integrator for MHD.

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

void integrate_destruct_1d ( void )

Free temporary integration arrays.
