Hello Prof. Sherwin,

I will recheck these modifications and submit a merge request. 

I also have a question about the simulation of flow around rotating bodies (such as bridge rotational VIV or flutter). I got stuck on setting up the case with the XYofXY coordinate transformation map (IncNavierStokesSolver produces segmentation fault) and haven't found related examples nor tutorials. I wonder if this approach is capable of simulating flow around rotating bodies in Nektar++ like in your papers (Li et al., 2002; Robertson et al., 2003a; Robertson et al., 2003b), or I made some mistakes in setting up the case (session file is also attached).
