const FArrayBox &  a_force,
const Real &  a_time,
const Real &  a_dt,
const Box &  a_box
)  [virtual]
 

apply source and returns max dt based on CFL condition

virtual int SelfGravityPhysics::bulkModulusIndex (   )  [virtual]

Transform a_dW from primitive to characteristic variables.

On input, a_dW contains the increments of the primitive variables. On output, it contains the increments in the characteristic variables.

IMPORTANT NOTE: It is assumed that the characteristic analysis puts the eigenvalues in order from smallest to largest and orders the eigenvalues and characteristic variables accordingly.

Implements GodunovPhysics.
