Hi Aleks,

thanks for the code, I looked over it and have two questions:
-at some point, it is mentioned that this method does not work if 
nelgt>nelgv. Why is that? I am asking because this will be applied to a 
conjugate HT problem (although the recycling part is purely concerning 
flow+convection). Will this problem also occur when only findpts is used 
instead of intpts?
-is there a performance difference between calling intpts as opposed to 
gs_op (as is done in the turbJet example) every time step for large 
scale production runs? The latter is what I used in my version.

Thanks,
Markus
