#2630: WaveMoL example computes energy from unsynchronized grid variables

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: major
Component: 

The WaveMoL example in CactusExamples computes the wave energy as `E = phi_t**2 + phi_i*phi_i` over the whole grid. However it does so on `MoL_PostStep` and ends up doing so before it applies boundary conditions and `SYNC` to the evolved variables \(`phi`, `phi_t` and `phi_i`\).
