Compute sources corresponding to a propagating front in user-defined box This function adds the energy source corresponding to a spherically growing wave-front propagating with a user-specified velocity, within a user-configured mesh block initial condition. Example (SI) units of the quantities involved:
- internal energy content (energy per unit volume): J/m^3
- specific energy (internal energy per unit mass): J/kg
