Surface Flow filter doesn't work with multi-block data
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
To reproduce this behavior, do the following.
Load combxyz.bin/comb.bin PLOT3D dataset. Apply a Cut filter to this.
In the Filter menu, the Surface Flow filter is not available. Somehow this worked in PV 2.6 because I came across this trying to duplicate the Flow.pvs test from the PV26 repository.
