Dear all,
 On the latest nektar version, 4.5.0, there is a problem with the given case (AcousticSolver/Tests/APE_2DPulseAdv_WeakDG_MODIFIED.xml). When the program runs，it will report an error "History point cannot be found in the mesh". However,
when the same xml file is used on a previous nektar version, 4.4.1, it is properly done. 

 The history point is not a node of mesh but in the domain. When i use a node of mesh as history point, the program performs well on the latest version. Can not use the points which are not nodes of mesh as history points now?

 Thank you.

 Cheers,
 Song
